What are the Factors of 53?

So, what are the factors of 53?

• Factors of 53: 1, 53

• Sum of Factors of 53: 54

• Negative Factors of 53: -1, -53

• Prime Factors of 53: 1, 53

• Prime Factorization of 53: 53

There are two ways to find the factors of 53: using factor pairs and using prime factorization.

Factor pairs of 53 are any two numbers that, when multiplied together, equal 53. The question to ask is “what two numbers multiplied together equal 53?” Every factor can be paired with another factor and multiplying the two will result in 53.

In this case, we can see that 53 is a prime number. By definition, a prime number is a number that doesn’t have any other factors other than itself and 1.

So, 53 only has one factor pair:

(1, 53)

If you also consider negative factors, there is also a second factor pair:

(-1, -53)

Prime factorization is when you break down the factors of 53 to just the prime factors and expressing 53 as a product of those prime factors.

In this case, because 53 is a prime number, we can simply state the primary factorization as 53.

For most numbers, we would take the smallest prime factor that is larger than 1 to start to break down the focus number. In this case, the smallest prime factor larger than 1 is 53.

53 ÷ 53 = 1

If we divide 53 by 53, we simply get 1, which can’t be broken down any further.

So, the prime factorization of 53 is just 53.
