Factor Calculator
Find all positive factors of a number, factor pairs, prime factorization, factor count, sum of factors, proper factors, and number type.
Positive integer from 1 to 10,000,000, without spaces or decimals.
Factors, factor pairs, and proper factors
For English users, factor calculator intent usually means listing every positive factor of a number, grouping factor pairs, and showing related values such as the factor count and sum of factors.
A factor d divides n when the remainder is 0.
- Enter a positive integer from 1 to 10,000,000.
- Use factor pairs to see which two numbers multiply to the input.
- Use proper factors when you need every positive factor except the number itself.
How the factor count is connected to prime factorization
The exponents in prime factorization determine the number of positive factors.
| Input | Positive factors |
|---|---|
| 24 | 1, 2, 3, 4, 6, 8, 12, 24 |
| 36 | 1, 2, 3, 4, 6, 9, 12, 18, 36 |
| 13 | 1, 13 |
