Calculate the Greatest Common Factor or GCF of 58, 60, 62 and 70
Sponsors
The instructions to find the GCF of 58, 60, 62 and 70 are the next:
1. Decompose all numbers into prime factors
| 58 | 2 |
| 29 | 29 |
| 1 |
| 60 | 2 |
| 30 | 2 |
| 15 | 3 |
| 5 | 5 |
| 1 |
| 62 | 2 |
| 31 | 31 |
| 1 |
| 70 | 2 |
| 35 | 5 |
| 7 | 7 |
| 1 |
2. Write all numbers as the product of its prime factors
| Prime factors of 58 | = | 2 . 29 |
| Prime factors of 60 | = | 22 . 3 . 5 |
| Prime factors of 62 | = | 2 . 31 |
| Prime factors of 70 | = | 2 . 5 . 7 |
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
