Definition of GCF
Greatest common factor commonly known as GCF of the two numbers is the highest possible number which completely divides given numbers, i.e. without leaving any remainder. It is represented as GCF (1150, 2000).
Properties of GCF
- Given two numbers 1150 and 2000, such that GCF is 50 where 50 will always be less than 1150 and 2000.
- GCF of two numbers is always equal to 1 in case given numbers are consecutive.
- The product of GCF and LCM of two given numbers is equal to the product of two numbers.
- The GCF of two given numbers is either 1 or the number itself if one of them is a prime number.
What are factors?
In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.
Properties of Factors
- Each number is a factor of itself. Eg. 1150 and 2000 are factors of themselves respectively.
- Every number other than 1 has at least two factors, namely the number itself and 1.
- Every factor of a number is an exact divisor of that number, example 1, 2, 5, 10, 23, 25, 46, 50, 115, 230, 575, 1150 are exact divisors of 1150 and 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 125, 200, 250, 400, 500, 1000, 2000 are exact divisors of 2000.
- 1 is a factor of every number. Eg. 1 is a factor of 1150 and also of 2000.
- Every number is a factor of zero (0), since 1150 x 0 = 0 and 2000 x 0 = 0.
Steps to find Factors of 1150 and 2000
- Step 1. Find all the numbers that would divide 1150 and 2000 without leaving any remainder. Starting with the number 1 upto 575 (half of 1150) and 1 upto 1000 (half of 2000). The number 1 and the number itself are always factors of the given number.
1150 ÷ 1 : Remainder = 0
2000 ÷ 1 : Remainder = 0
1150 ÷ 2 : Remainder = 0
2000 ÷ 2 : Remainder = 0
1150 ÷ 5 : Remainder = 0
2000 ÷ 4 : Remainder = 0
1150 ÷ 10 : Remainder = 0
2000 ÷ 5 : Remainder = 0
1150 ÷ 23 : Remainder = 0
2000 ÷ 8 : Remainder = 0
1150 ÷ 25 : Remainder = 0
2000 ÷ 10 : Remainder = 0
1150 ÷ 46 : Remainder = 0
2000 ÷ 16 : Remainder = 0
1150 ÷ 50 : Remainder = 0
2000 ÷ 20 : Remainder = 0
1150 ÷ 115 : Remainder = 0
2000 ÷ 25 : Remainder = 0
1150 ÷ 230 : Remainder = 0
2000 ÷ 40 : Remainder = 0
1150 ÷ 575 : Remainder = 0
2000 ÷ 50 : Remainder = 0
1150 ÷ 1150 : Remainder = 0
2000 ÷ 80 : Remainder = 0
2000 ÷ 100 : Remainder = 0
2000 ÷ 125 : Remainder = 0
2000 ÷ 200 : Remainder = 0
2000 ÷ 250 : Remainder = 0
2000 ÷ 400 : Remainder = 0
2000 ÷ 500 : Remainder = 0
2000 ÷ 1000 : Remainder = 0
2000 ÷ 2000 : Remainder = 0
Hence, Factors of
1150 are 1, 2, 5, 10, 23, 25, 46, 50, 115, 230, 575, and 1150
And, Factors of
2000 are 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 125, 200, 250, 400, 500, 1000, and 2000
Examples of GCF
Sammy baked 1150 chocolate cookies and 2000 fruit and nut cookies to package in plastic containers for her friends at college. She wants to divide the cookies into identical boxes so that each box has the same number of each kind of cookies. She wishes that each box should have greatest number of cookies possible, how many plastic boxes does she need?Since Sammy wants to pack greatest number of cookies possible. So for calculating total number of boxes required we need to calculate the GCF of 1150 and 2000.
GCF of 1150 and 2000 is 50.
A class has 1150 boys and 2000 girls. A choir teacher wants to form a choir team from this class such that the students are standing in equal rows also girls or boys will be in each row. Teacher wants to know the greatest number of students that could be in each row, can you help him?To find the greatest number of students that could be in each row, we need to find the GCF of 1150 and 2000. Hence, GCF of 1150 and 2000 is 50.
What is the difference between GCF and LCM?Major and simple difference betwen GCF and LCM is that GCF gives you the greatest common factor while LCM finds out the least common factor possible for the given numbers.
What is the relation between LCM and GCF (Greatest Common Factor)?GCF and LCM of two numbers can be related as GCF(1150, 2000) = ( 1150 * 2000 ) / LCM(1150, 2000) = 50.
What is the GCF of 1150 and 2000?GCF of 1150 and 2000 is 50.
Ariel is making ready to eat meals to share with friends. She has 1150 bottles of water and 2000 cans of food, which she would like to distribute equally, with no left overs. What is the greatest number of boxes Ariel can make?The greatest number of boxes Ariel can make would be equal to GCF of 1150 and 2000. So the GCF of 1150 and 2000 is 50.
Mary has 1150 blue buttons and 2000 white buttons. She wants to place them in identical groups without any buttons left, in the greatest way possible. Can you help Mary arranging them in groups?Greatest possible way in which Mary can arrange them in groups would be GCF of 1150 and 2000. Hence, the GCF of 1150 and 2000 or the greatest arrangement is 50.
Kamal is making identical balloon arrangements for a party. He has 1150 maroon balloons, and 2000 orange balloons. He wants each arrangement tohave the same number of each color. What is the greatest number of arrangements that he can make if every balloon is used?The greatest number of arrangements that he can make if every balloon is used would be equal to GCF of 1150 and 2000. So the GCF of 1150 and 2000 is 50.
Kunal is making baskets full of nuts and dried fruits. He has 1150 bags of nuts and 2000 bags of dried fruits. He wants each basket to be identical, containing the same combination of bags of nuts and bags of driesn fruits, with no left overs. What is the greatest number of baskets that Kunal can make?the greatest number of baskets that Kunal can make would be equal to GCF of 1150 and 2000. So the GCF of 1150 and 2000 is 50.
