Factors of 131
In mathematics, factors of 131 are numbers that multiply together to make 131. For example, 1 × 131 = 131, so both 1 and 131 are factors. Every number has at least two factors: 1 and itself. These factors always divide 131 completely without leaving a remainder. To find them, you can use basic division or break the number into prime factors. Learning about the factors of 131 helps with understanding multiplication, greatest common factors (GCF), and prime factorization. Let’s explore all the factors, factor pairs, and prime factors of 131 with clear examples.
What are the Factors of 131?
When we talk about the factors of 131, we’re referring to numbers that divide it evenly. These are 1 and 131. If we also consider negative divisors, we get -1 and -131. Each factor pairs with another to make 131. This idea of factorization is key in number theory, it tells us whether 131 is prime or composite. Since 131 has only two factors (1 and itself), it’s recognized as a prime number one of the building blocks of all numbers.

Factor Pairs of 131
Factor pairs of 131 are pairs of numbers that, when multiplied, result in 131. These pairs come in both positive and negative forms. For example, the positive pairs are (1, 131), and the negative ones are (-1, -131). Recognizing these pairs helps you see how 131 is structured mathematically and improves understanding of how numbers relate through multiplication and division. This concept is also helpful when finding the greatest common factor or simplifying fractions. You can also explore how factor pairs relate to the greatest common factor and prime factorization for deeper understanding.
