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 (15, 135).

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 15 and 135, such that GCF is 15 where 15 will always be less than 15 and 135.
Product of two numbers is always equal to the product of their GCF and LCM.

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

Every number is a factor of zero (0), since 15 x 0 = 0 and 135 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, 3, 5, 15 are exact divisors of 15 and 1, 3, 5, 9, 15, 27, 45, 135 are exact divisors of 135.
Factors of 15 are 1, 3, 5, 15. Each factor divides 15 without leaving a remainder.
Simlarly, factors of 135 are 1, 3, 5, 9, 15, 27, 45, 135. Each factor divides 135 without leaving a remainder.

Steps to find Factors of 15 and 135

Step 1. Find all the numbers that would divide 15 and 135 without leaving any remainder. Starting with the number 1 upto 7 (half of 15) and 1 upto 67 (half of 135). The number 1 and the number itself are always factors of the given number.

15 ÷ 1 : Remainder = 0

135 ÷ 1 : Remainder = 0

15 ÷ 3 : Remainder = 0

135 ÷ 3 : Remainder = 0

15 ÷ 5 : Remainder = 0

135 ÷ 5 : Remainder = 0

15 ÷ 15 : Remainder = 0

135 ÷ 9 : Remainder = 0

135 ÷ 15 : Remainder = 0

135 ÷ 27 : Remainder = 0

135 ÷ 45 : Remainder = 0

135 ÷ 135 : Remainder = 0

Hence, Factors of 15 are 1, 3, 5, and 15

And, Factors of 135 are 1, 3, 5, 9, 15, 27, 45, and 135

Examples of GCF

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

GCF and LCM of two numbers can be related as GCF(15, 135) = ( 15 * 135 ) / LCM(15, 135) = 15.

What is the GCF of 15 and 135?

GCF of 15 and 135 is 15.

Ram has 15 cans of Pepsi and 135 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 15 and 135. Hence GCF of 15 and 135 is 15. So the number of tables that can be arranged is 15.

Rubel is creating individual servings of starters for her birthday party. He has 15 pizzas and 135 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 15 and 135. Thus GCF of 15 and 135 is 15.
