Find the Factors of a Number
What Are Factors?
Factors are whole numbers that divide another number exactly without leaving a remainder. Every positive integer has at least two factors: 1 and the number itself.
For example, the factors of 12 are 1, 2, 3, 4, 6, and 12. Each of these numbers divides 12 evenly.
3 × 4 = 12, so both 3 and 4 are factors of 12.
How to Use the Factors Calculator
Finding factors manually can become time-consuming for larger numbers. This calculator gives you the complete factor list instantly.
- Enter a positive whole number.
- Click the Find Factors button.
- View all factors of the number.
- Review the factor pairs.
- Check the prime factorization.
How Does the Factors Calculator Work?
The calculator checks whole numbers that can divide the input number without producing a remainder. When a number divides evenly, both the divisor and its corresponding quotient form a factor pair.
For example, consider the number 24. The factor pairs are:
1 × 24 = 24
2 × 12 = 24
3 × 8 = 24
4 × 6 = 24
Therefore, the positive factors of 24 are: 1, 2, 3, 4, 6, 8, 12, and 24.
The calculator also determines the prime factorization of the number by breaking it down into its prime factors.
What Is Prime Factorization?
Prime factorization is the process of expressing a number as a product of prime numbers.
For example, 60 can be broken down as:
Or using exponents: 60 = 2² × 3 × 5.
