Sponsors
The instructions to find the GCF of 23, 69, 92 and 115 are the next:
1. Decompose all numbers into prime factors
| 23 | 23 |
| 1 |
| 69 | 3 |
| 23 | 23 |
| 1 |
| 92 | 2 |
| 46 | 2 |
| 23 | 23 |
| 1 |
| 115 | 5 |
| 23 | 23 |
| 1 |
2. Write all numbers as the product of its prime factors
| Prime factors of 23 | = | 23 |
| Prime factors of 69 | = | 3 . 23 |
| Prime factors of 92 | = | 22 . 23 |
| Prime factors of 115 | = | 5 . 23 |
3. Choose the common prime factors with the lowest exponent
Common prime factors: 23
Common prime factors with the lowest exponent: 231
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 = 231 = 23
