Common Factors Calculator
Find all common factors for two or more positive integers, including the GCF, each number's factors, and relatively-prime checks.
Find every common factor
English search intent for common factors usually expects the complete shared factor list, not only the largest factor. This calculator lists the factors of each input, highlights the intersection, and shows the GCF.
All common factors of a set are the factors of the set's greatest common factor.
- Enter at least two positive integers.
- Review the highlighted common factors.
- Use the GCF result when you need the largest shared factor.
GCF, GCD, and common divisors
| Input | Common factors | GCF |
|---|---|---|
| 24, 36 | 1, 2, 3, 4, 6, 12 | 12 |
| 24, 36, 60 | 1, 2, 3, 4, 6, 12 | 12 |
| 8, 15 | 1 | 1 |
