What is GCF of two numbers?

In mathematics GCF or also known as greatest common factor of two or more number is that one largest number which is a factor of those given numbers. It is represented as GCF (91, 156).

Properties of GCF

The GCF of two given numbers where one of them is a prime number is either 1 or the number itself.
GCF of two consecutive numbers is always 1.
Given two numbers 91 and 156, such that GCF is 13 where 13 will always be less than 91 and 156.
Product of two numbers is always equal to the product of their GCF and LCM.

How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

Properties of Factors

Every number is a factor of zero (0), since 91 x 0 = 0 and 156 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, 7, 13, 91 are exact divisors of 91 and 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156 are exact divisors of 156.
Factors of 91 are 1, 7, 13, 91. Each factor divides 91 without leaving a remainder.
Simlarly, factors of 156 are 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156. Each factor divides 156 without leaving a remainder.

Steps to find Factors of 91 and 156

Step 1. Find all the numbers that would divide 91 and 156 without leaving any remainder. Starting with the number 1 upto 45 (half of 91) and 1 upto 78 (half of 156). The number 1 and the number itself are always factors of the given number.

91 ÷ 1 : Remainder = 0

156 ÷ 1 : Remainder = 0

91 ÷ 7 : Remainder = 0

156 ÷ 2 : Remainder = 0

91 ÷ 13 : Remainder = 0

156 ÷ 3 : Remainder = 0

91 ÷ 91 : Remainder = 0

156 ÷ 4 : Remainder = 0

156 ÷ 6 : Remainder = 0

156 ÷ 12 : Remainder = 0

156 ÷ 13 : Remainder = 0

156 ÷ 26 : Remainder = 0

156 ÷ 39 : Remainder = 0

156 ÷ 52 : Remainder = 0

156 ÷ 78 : Remainder = 0

156 ÷ 156 : Remainder = 0

Hence, Factors of 91 are 1, 7, 13, and 91

And, Factors of 156 are 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, and 156

Examples of GCF

Sammy baked 91 chocolate cookies and 156 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 91 and 156.
GCF of 91 and 156 is 13.

A class has 91 boys and 156 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 91 and 156. Hence, GCF of 91 and 156 is 13.

What is the relation between LCM and GCF (Greatest Common Factor)?

GCF and LCM of two numbers can be related as GCF(91, 156) = ( 91 * 156 ) / LCM(91, 156) = 13.

What is the GCF of 91 and 156?

GCF of 91 and 156 is 13.

Ram has 91 cans of Pepsi and 156 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 91 and 156. Hence GCF of 91 and 156 is 13. So the number of tables that can be arranged is 13.

Mary has 91 blue buttons and 156 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 91 and 156. Hence, the GCF of 91 and 156 or the greatest arrangement is 13.

Kamal is making identical balloon arrangements for a party. He has 91 maroon balloons, and 156 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 91 and 156. So the GCF of 91 and 156 is 13.

Kunal is making baskets full of nuts and dried fruits. He has 91 bags of nuts and 156 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 91 and 156. So the GCF of 91 and 156 is 13.
