Factors of 23

Factors of 23 are numbers that equally divide the original number. When two multiplied numbers give the same answer, they are called pair factors.

Factors 23 are 1 and 23.

Its factors are only two since 23 is a prime number. Natural numbers make up the number 23, but it is not a fraction or decimal number.

How to Find the Factors of 23?

We will use the factorization method to find the factors of the number 23.

To use the factorization method, first, consider the numbers 1 and 23 as factors of 23 and then find the other pair of multiples of 23, resulting in the original number. 

Find the factors of 23 by following these steps.

  • Write the number 23 first.
  • You need to find two numbers that result in 23 when multiplied, say 1 and 23, so that 1 × 23 = 23.
  • 1 and 23 are the only two prime numbers with just two factors, namely, one and themselves, and cannot be factored any further.

The factors of 23 = 23 × 1

  • Thus, 23 is factorized as 23 × 1

Pair Factors of 23

You can find the pair factors of 23 by multiplying two numbers to get 23. As shown below, we can write both positive and negative integers in pairs:

Positive pairsNegative pairs
1 × 23 = 23;     (1, 23)(-1) × (-23) = 23;       (-1, -23)
23 × 1 = 23;     (23, 1)(-23) × (-1) = 23;       (-23, -1)

Accordingly, 23 has two positive pair factors: (1, 23) and (23, 1).

There are two negative pair factors for 23: (-1, -23) and (-23, -1).

Prime Factors of 23

We generally use the prime factorization method to find the prime factors of a number. In this case, 23 has the following prime factors.

23 = 1 × 23

23 is one of the prime numbers. As the prime numbers only have one factor themselves, we cannot factor them further.

Thus, 23 alone is the prime factor.
