What is a factor?
A factor is any integer that divides another number evenly with no remainder. Every positive integer has at least two factors: 1 and itself.
For example, 12 has factors 1, 2, 3, 4, 6, and 12. You can verify: 12/1=12, 12/2=6, 12/3=4, and so on - all whole numbers.
Using the factor calculator
Enter any positive integer and the calculator instantly displays all its factors. Factors highlighted in yellow are prime numbers - numbers divisible only by 1 and themselves.
The tool also shows:
- Total factor count - how many divisors the number has
- Prime factors - count of factors that are prime
- Sum of factors - useful for perfect number identification
- Prime check - whether the input itself is prime
Switch to Prime Factorization mode to see the number broken down into its prime components with exponents.
