Given numbers are 648, 4860
The greatest common factor of 648, 4860 can be found by using the following 2 different methods.
The GCF of 648, 4860 is 324.
Prime factorization is basically division by prime numbers only. Keep dividing all numbers by the same prime number, until the numbers can no longer be divided by a single prime number. Then, multiply all the prime numbers that are on the left side.
2 | 648, 4860 |
2 | 324, 2430 |
3 | 162, 1215 |
3 | 54, 405 |
3 | 18, 135 |
3 | 6, 45 |
2, 15 |
∴ Thus, the GCF of given numbers is 2 x 2 x 3 x 3 x 3 x 3 = 324
