The factors of these numbers are: 1 1, 2 1, 3 1, 2, 3, 6 1, 3, 9
All of the numbers from 1 to 100 are the factors in the set of numbers from 2 to 100.
Factors refer to whole numbers, not mixed numbers.
The factors of 13 are 1 and 13. The factors of 2 are 1 and 2. Both 13 and 2 are prime numbers.
1 and 2

The only number that is a factor of all the numbers from 1 to 100 is the number 1. The only factor of 1 is 1. The factors of 2 are 1 and 2. The factors of 3 are 1 and 3. The factors of 4 are 1, 2, and 4. The factors of 5 are 1 and 5. The factors of 6 are 1, 2, 3, and 6. The factors of 7 are 1 and 7. The factors of 8 are 1, 2, 4, and 8. The factors of 9 are 1, 3, and 9. The factors of 10 are 1, 2, 5, and 10. The only common factor of these ten numbers is 1. Since all numbers are divisible by 1, the greatest common factor is 1.
The other factors could be 4 and 5 or 1 and 20.
