Factors of 43
In mathematics, factors of 43 are numbers that multiply together to make 43. For example, 1 × 43 = 43, so both 1 and 43 are factors. Every number has at least two factors: 1 and itself. These factors always divide 43 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 43 helps with understanding multiplication, greatest common factors (GCF), and prime factorization. Let’s explore all the factors, factor pairs, and prime factors of 43 with clear examples.
What are the Factors of 43?
When we talk about the factors of 43, we’re referring to numbers that divide it evenly. These are 1 and 43. If we also consider negative divisors, we get -1 and -43. Each factor pairs with another to make 43. This idea of factorization is key in number theory, it tells us whether 43 is prime or composite. Since 43 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 43
Factor pairs of 43 are pairs of numbers that, when multiplied, result in 43. These pairs come in both positive and negative forms. For example, the positive pairs are (1, 43), and the negative ones are (-1, -43). Recognizing these pairs helps you see how 43 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.
