Sponsors
The instructions to find the GCF of 6, 100, 106 and 124 are the next:
1. Decompose all numbers into prime factors
| 6 | 2 |
| 3 | 3 |
| 1 |
| 100 | 2 |
| 50 | 2 |
| 25 | 5 |
| 5 | 5 |
| 1 |
| 106 | 2 |
| 53 | 53 |
| 1 |
| 124 | 2 |
| 62 | 2 |
| 31 | 31 |
| 1 |
2. Write all numbers as the product of its prime factors
| Prime factors of 6 | = | 2 . 3 |
| Prime factors of 100 | = | 22 . 52 |
| Prime factors of 106 | = | 2 . 53 |
| Prime factors of 124 | = | 22 . 31 |
3. Choose the common prime factors with the lowest exponent
Common prime factors: 2
Common prime factors with the lowest exponent: 21
4. Calculate the Greatest Common Factor or GCF
Remember, to find the GCF of several numbers you must multiply the common prime factors with the lowest exponent.
GCF = 21 = 2
