As your math tutor, I’m here to guide you through the different types of factors of 157. So, what are the factors of 157?
• Factors of 157: 1, 157
• Sum of Factors of 157: 158
• Negative Factors of 157: -1, -157
• Prime Factors of 157: 1, 157
• Prime Factorization of 157: 157
There are two ways to find the factors of 157: using factor pairs and using prime factorization.
Factor pairs of 157 are any two numbers that, when multiplied together, equal 157. The question I would ask as a math tutor to guide you is: “what two numbers multiplied together equal 157?” Every factor can be paired with another factor and multiplying the two will result in 157.
In this case, we can see that 157 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, 157 only has one factor pair:
(1, 157)
If you also consider negative factors, there is also a second factor pair:
(-1, -157)
Prime factorization is when you break down the factors of 157 to just the prime factors and expressing 157 as a product of those prime factors. Let’s go through the process and simplify it like a math tutor would!
In this case, because 157 is a prime number, we can simply state the primary factorization as 157.
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 157.
157 ÷ 157 = 1
If we divide 157 by 157, we simply get 1, which can’t be broken down any further.
So, the prime factorization of 157 is just 157.
Practice your factoring skills by exploring how to factor other numbers, like the ones below:
Factors of 56 - The factors of 56 are 1, 2, 4, 7, 8, 14, 28, 56
Factors of 125 - The factors of 125 are 1, 5, 25, 125
Factors of 20 - The factors of 20 are 1, 2, 4, 5, 10, 20
Factors of 136 - The factors of 136 are 1, 2, 4, 8, 17, 34, 68, 136
