Factor Calculator
The Factor Calculator helps you find all factors and prime factors of a given integer. Factors are numbers that divide the original number completely without leaving a remainder.
What is a Factor?
A factor is an integer that divides another integer exactly without leaving any remainder. In simple multiplication terms, if two numbers are multiplied to produce a result, both numbers are factors of that result.
For example: 6 × 5 = 30, so 6 and 5 are factors of 30.

Prime Factorization
Prime factorization is the process of breaking a number down into its prime numbers. These prime numbers, when multiplied together, give the original number.
For 120, the prime factorization is: 2 × 2 × 2 × 3 × 5
Factor Tree Method
A factor tree is a visual method used to break numbers into prime factors step by step.
- Start with the original number (120)
- Split it into two factors
- Continue breaking until all numbers are prime
Why Factors are Important
- Simplifying fractions
- Finding LCM and GCF
- Solving algebraic equations
- Understanding number patterns
Prime Numbers in Factorization
Prime numbers are numbers greater than 1 that have only two factors: 1 and themselves. They are the building blocks of all integers.
Examples of prime numbers: 2, 3, 5, 7, 11, 13...
Limitations of Prime Factorization
For very large numbers, prime factorization becomes very complex and time-consuming. Even modern computers require significant time for extremely large integers.
