# Factors of 1 to 100

Factors of 1 to 100 are provided here. All the composite numbers have more than two factors and prime numbers have only two factors, i.e, 1 and the number itself. Prime factors of a number are the prime numbers that can divide the original number, uniformly.

## Table of Factors of 1 to 100

The factors of all the natural numbers from 1 to 100 are given below along with their prime factor form. Also, see, which of the natural numbers are prime numbers and which are composite numbers.
