Here is a handy little GCF Calculator that you can use to find the GCF of two numbers 4, 8 i.e. 4 the largest number that divides both the numbers exactly.
Greatest Common Factor of 4 and 8 is 4
GCF(4, 8) = 4
Ex: number 1 - 1500 and number 2 - 20.
Given Inputs are 4, 8
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 4 as under
| 2 | 4 |
| 2 | 2 |
| 1 |
Prime factors of 4 are 2. Prime factorization of 4 in exponential form is:
4 = 22
Prime Factorization of 8 is as such
| 2 | 8 |
| 2 | 4 |
| 2 | 2 |
| 1 |
Prime factors of 8 are 2.Prime factorization of 8 in exponential form is:
8 = 23
Occurrences of Common Prime Factors from both the numbers 4 and 8 is 4
Therefore, GCF of two numbers 4 and 8 is 4
Given input data is 4, 8
Make a list of factors for the corresponding input numbers
Factors of 4
List of positive integer factors of 4 that divides 4 without a remainder.
1,2,4
Factors of 8
List of positive integer factors of 8 that divides 8 without a remainder.
1,2,4,8
Figure out the highest common factor from factors of both the numbers and that is the GCF. In this case, it is 4
Therefore, GCF of two numbers 4 ad 8 is 4
