How do you explain factors?
In mathematics, a factor is a number or also it can be an algebraic expression that divides another number or any expression completely and that too without leaving any remainder. A factor of a number can be positive or negative.
Properties of Factors
- Each number is a factor of itself. Eg. 112 and 144 are factors of themselves respectively.
- 1 is a factor of every number. Eg. 1 is a factor of 112 and also of 144.
- Every number is a factor of zero (0), since 112 x 0 = 0 and 144 x 0 = 0.
- 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, 4, 7, 8, 14, 16, 28, 56, 112 are exact divisors of 112 and 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144 are exact divisors of 144.
- Factors of 112 are 1, 2, 4, 7, 8, 14, 16, 28, 56, 112. Each factor divides 112 without leaving a remainder.
Simlarly, factors of 144 are 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144. Each factor divides 144 without leaving a remainder. - Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 7, 8, 14, 16, 28, 56, 112 are all less than or equal to 112 and 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144 are all less than or equal to 144.
Steps to find Factors of 112 and 144
- Step 1. Find all the numbers that would divide 112 and 144 without leaving any remainder. Starting with the number 1 upto 56 (half of 112) and 1 upto 72 (half of 144). The number 1 and the number itself are always factors of the given number.
112 ÷ 1 : Remainder = 0
144 ÷ 1 : Remainder = 0
112 ÷ 2 : Remainder = 0
144 ÷ 2 : Remainder = 0
112 ÷ 4 : Remainder = 0
144 ÷ 3 : Remainder = 0
112 ÷ 7 : Remainder = 0
144 ÷ 4 : Remainder = 0
112 ÷ 8 : Remainder = 0
144 ÷ 6 : Remainder = 0
112 ÷ 14 : Remainder = 0
144 ÷ 8 : Remainder = 0
112 ÷ 16 : Remainder = 0
144 ÷ 9 : Remainder = 0
112 ÷ 28 : Remainder = 0
144 ÷ 12 : Remainder = 0
112 ÷ 56 : Remainder = 0
144 ÷ 16 : Remainder = 0
112 ÷ 112 : Remainder = 0
144 ÷ 18 : Remainder = 0
144 ÷ 144 : Remainder = 0
Hence, Factors of
112 are 1, 2, 4, 7, 8, 14, 16, 28, 56, and 112
And, Factors of
144 are 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144
Examples of GCF
Sammy baked 112 chocolate cookies and 144 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 112 and 144.
GCF of 112 and 144 is 16.
A class has 112 boys and 144 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 112 and 144. Hence, GCF of 112 and 144 is 16.
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(112, 144) = ( 112 * 144 ) / LCM(112, 144) = 16.
What is the GCF of 112 and 144?GCF of 112 and 144 is 16.
Mary has 112 blue buttons and 144 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 112 and 144. Hence, the GCF of 112 and 144 or the greatest arrangement is 16.
Kamal is making identical balloon arrangements for a party. He has 112 maroon balloons, and 144 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 112 and 144. So the GCF of 112 and 144 is 16.
Kunal is making baskets full of nuts and dried fruits. He has 112 bags of nuts and 144 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 112 and 144. So the GCF of 112 and 144 is 16.
To energize public transportation, Abir needs to give a few companions envelopes with transport tickets, and metro tickets in them. On the off chance that he has 112 bus tickets and 144 metro tickets to be parted similarly among the envelopes, and he need no tickets left. What is the greatest number of envelopes Abir can make?To make the greatest number of envelopes Abir needs to find out the GCF of 112 and 144. Hence, GCF of 112 and 144 is 16.
