What Are the Factors of a Number?
A factor is a whole number that divides another number exactly,
with no remainder. Enter a positive whole number below to find
its factors.
Quick example: factors of 12
1, 2, 3, 4, 6, 12
1, 2, 3, 4, 6, 12
Each number in the list divides 12 evenly. For example,
12 ÷ 3 = 4 and 12 ÷ 4 = 3.

Examples of Factors
| Number | Positive factors |
|---|---|
| 12 | 1, 2, 3, 4, 6, 12 |
| 18 | 1, 2, 3, 6, 9, 18 |
| 24 | 1, 2, 3, 4, 6, 8, 12, 24 |
| 36 | 1, 2, 3, 4, 6, 9, 12, 18, 36 |
How Do You Find the Factors of a Number?
Look for whole-number pairs whose product is the number.
For 24, the pairs are 1 × 24,
2 × 12, 3 × 8, and
4 × 6. Put every number from these pairs
in one list to get all the positive factors of 24.
Factors vs. Prime Factors
All factors of 12: 1, 2, 3, 4, 6, 12.
Prime factorization of 12: 2 × 2 × 3.
Prime factorization shows the prime numbers whose product
is 12; it is different from listing every factor.
