131 is a Prime number. A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. To confirm that 131 is a prime number, you can check whether it can be evenly divided by all the prime numbers less than or equal to the integer part of its square root; in other words, 2, 3, 5, 7, and 11.
