Finding GCF of two Numbers using Factoring Method
In order to find the GCF of two numbers using Factoring Methos firstly list out all the factors of each number. Factors are the numbers that divide the number evenly i.e. leaving a remainder zero. In the Common Factor List of given numbers, GCF is the largest number common to each of the lists.
Find the GCF of numbers 18, 27?
Given Inputs are 18, 27
Initially, find the factors of both the numbers 18, 27
Factors of 18 are 1, 2, 3, 6, 9, 18
Factors of 27 are 1, 3, 9, 27
Common Factors of 18, 27 are 1, 3, 9
In the factors of both the numbers, GCF is 9 as it is the largest number common to each of the lists.
Therefore, GCF of two numbers 18, 27 is 9
