Here is a handy little GCF Calculator that you can use to find the GCF of two numbers 6, 18 i.e. 6 the largest number that divides both the numbers exactly.
Greatest Common Factor of 6 and 18 is 6
GCF(6, 18) = 6
Ex: number 1 - 1500 and number 2 - 20.
Given Inputs are 6, 18
To find the GCF using the Prime Factorization Method you just need to list out the prime factors of both the numbers.
Prime Factorization of 6 as under
| 2 | 6 |
| 3 | 3 |
| 1 |
Prime factors of 6 are 2,3. Prime factorization of 6 in exponential form is:
6 = 21×31
Prime Factorization of 18 is as such
| 2 | 18 |
| 3 | 9 |
| 3 | 3 |
| 1 |
Prime factors of 18 are 2,3. Prime factorization of 18 in exponential form is:
18 = 21×32
Occurrences of Common Prime Factors from both the numbers 6 and 18 is 6
Therefore, GCF of two numbers 6 and 18 is 6
Given input data is 6, 18
Make a list of factors for the corresponding input numbers
Factors of 6
