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 (630, 712).
Properties of GCF
- Given two numbers 630 and 712, such that GCF is 2 where 2 will always be less than 630 and 712.
- 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. 630 and 712 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, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630 are exact divisors of 630 and 1, 2, 4, 8, 89, 178, 356, 712 are exact divisors of 712.
- 1 is a factor of every number. Eg. 1 is a factor of 630 and also of 712.
- Every number is a factor of zero (0), since 630 x 0 = 0 and 712 x 0 = 0.
Steps to find Factors of 630 and 712
- Step 1. Find all the numbers that would divide 630 and 712 without leaving any remainder. Starting with the number 1 upto 315 (half of 630) and 1 upto 356 (half of 712). The number 1 and the number itself are always factors of the given number.
630 ÷ 1 : Remainder = 0
712 ÷ 1 : Remainder = 0
630 ÷ 2 : Remainder = 0
712 ÷ 2 : Remainder = 0
630 ÷ 3 : Remainder = 0
712 ÷ 4 : Remainder = 0
630 ÷ 5 : Remainder = 0
712 ÷ 8 : Remainder = 0
630 ÷ 6 : Remainder = 0
712 ÷ 89 : Remainder = 0
630 ÷ 7 : Remainder = 0
712 ÷ 178 : Remainder = 0
630 ÷ 9 : Remainder = 0
712 ÷ 356 : Remainder = 0
630 ÷ 10 : Remainder = 0
712 ÷ 712 : Remainder = 0
630 ÷ 105 : Remainder = 0
630 ÷ 126 : Remainder = 0
630 ÷ 210 : Remainder = 0
630 ÷ 315 : Remainder = 0
630 ÷ 630 : Remainder = 0
Hence, Factors of
630 are 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, and 630
And, Factors of
712 are 1, 2, 4, 8, 89, 178, 356, and 712
Examples of GCF
Sammy baked 630 chocolate cookies and 712 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 630 and 712.
GCF of 630 and 712 is 2.
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(630, 712) = ( 630 * 712 ) / LCM(630, 712) = 2.
What is the GCF of 630 and 712?GCF of 630 and 712 is 2.
Ram has 630 cans of Pepsi and 712 cans of Coca Cola. He wants to create identical refreshment tables that will be organized in his house warming party. He also doesn't want to have any can left over. What is the greatest number of tables that Ram can arrange?To find the greatest number of tables that Ram can stock we need to find the GCF of 630 and 712. Hence GCF of 630 and 712 is 2. So the number of tables that can be arranged is 2.
Rubel is creating individual servings of starters for her birthday party. He has 630 pizzas and 712 hamburgers. He wants each serving to be identical, with no left overs. Can you help Rubel in arranging the same in greatest possible way?The greatest number of servings Rubel can create would be equal to the GCF of 630 and 712. Thus GCF of 630 and 712 is 2.
Ariel is making ready to eat meals to share with friends. She has 630 bottles of water and 712 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 630 and 712. So the GCF of 630 and 712 is 2.
Mary has 630 blue buttons and 712 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 630 and 712. Hence, the GCF of 630 and 712 or the greatest arrangement is 2.
Kamal is making identical balloon arrangements for a party. He has 630 maroon balloons, and 712 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 630 and 712. So the GCF of 630 and 712 is 2.
