What are the Factors of 7?
As your math tutor, I’m here to guide you through the different types of factors of 7. So, what are the factors of 7?
• Factors of 7: 1, 7
• Sum of Factors of 7: 8
• Negative Factors of 7: -1, -7
• Prime Factors of 7: 1, 7
• Prime Factorization of 7: 7
There are two ways to find the factors of 7: using factor pairs and using prime factorization.
The Factor Pairs of 7
Factor pairs of 7 are any two numbers that, when multiplied together, equal 7. The question I would ask as a math tutor to guide you is: “what two numbers multiplied together equal 7?” Every factor can be paired with another factor and multiplying the two will result in 7.
In this case, we can see that 7 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, 7 only has one factor pair:
(1, 7)
If you also consider negative factors, there is also a second factor pair:
(-1, -7)
Prime Factorization of 7
Prime factorization is when you break down the factors of 7 to just the prime factors and expressing 7 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 7 is a prime number, we can simply state the primary factorization as 7.
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 7.
7 ÷ 7 = 1
If we divide 7 by 7, we simply get 1, which can’t be broken down any further.
So, the prime factorization of 7 is just 7.
Math Tutor Suggests: Find the Factors of Other Numbers
Practice your factoring skills by exploring how to factor other numbers, like the ones below:
Factors of 139 - The factors of 139 are 1, 139
Factors of 147 - The factors of 147 are 1, 3, 7, 21, 49, 147
Factors of 140 - The factors of 140 are 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
Factors of 32 - The factors of 32 are 1, 2, 4, 8, 16, 32
