What Are the Factors of 43?
Let us recall the meaning of the term 'factor'. A factor is a number that divides the number into equal parts. Factors of 43 are the numbers which when multiplied together give the product as 43. 43 has only two factors and they are 1 and 43. The number 43 is a prime number.
How to Calculate the Factors of 43?
- Let's begin calculating the factors of 43, starting with the smallest natural number, i.e., 1. Divide 43 with this number. Is the remainder 0? Yes! So, we will get, 43 ÷ 1 = 43
- The next natural number is 2. Now, divide 43 with this number. Is the remainder 0? Definitely NO!
- Can you find another number that can divide 43 equally?
- 43 is a prime number because it has two factors only, that is, 1 and the number itself.

Important Notes
- Factors of any number are all the possible divisible numbers. They may be prime numbers or composite numbers.
- Factors are always integers except 0. They are never fractions or decimals.
- 1 and the number itself are factors of a number because they exactly divide the given number.
Factors of 43 by Prime Factorization
We just learned that 43 is a prime number. It has only 2 factors, 1 and the number itself.
So the prime factorization of the number 43 is written as the number 43 (itself).
Factors of 43 in Pairs
- The positive pair factors of 43 are (1, 43) and (43, 1). Both the factor pairs (1, 43) and (43, 1) are the same.
- If we consider negative integers, then both the numbers in the pair factors will be negative.
- 43 is a positive number and we know that the product of two negative numbers is a positive number.
- Therefore, we can have factor pairs of 43 as (-1,-43) and (-43,-1). Both the pairs are the same.
- Since 43 is a prime number, we don't have any other factor pair.
FAQs on Factors of 43
