Factors of 120 | Understanding Factors and Their Significance
Before we dive into the factors of 120, let’s establish a profound understanding of what factors represent. Factors are integers that divide a number exactly, leaving no remainder.
They play a pivotal role in numerous mathematical concepts and applications, including prime numbers, greatest common divisors, and simplifying fractions. Factors, in essence, are the fundamental elements of numbers, shaping the foundation of mathematics.
How to Find the Factors of 120?
Understanding the methods for identifying the factors of 120 is key to our exploration.
Method 1: Brute Force
The simplest method is to test each integer from 1 to 120 to see if it divides 120 evenly. While effective, this technique becomes time-consuming for larger numbers.
Method 2: Prime Factorization
A more systematic approach involves finding the prime factors of 120 and using them to derive all factors. For 120, the prime factors are 2, 2, 2, 3, and 5. By multiplying these prime factors in different combinations, we can find all the factors of 120:
- 2×2×2×3×5=120
Utilizing prime factorization, we’ve unveiled the factors of 120.
Method 3: Division Method
Another approach is to use division. Starting with 1, we divide 120 by progressively larger integers until we’ve covered all the factors:
- 120÷1=120
- 120÷2=60
- 120÷3=40
- 120÷4=30
- 120÷5=24
- 120÷6=20
- 120÷8=15
Continuing this process reveals all factors of 120.

Factors of 120 in Pairs
The factor pairs of 120 refer to all the different combinations of the two factors of 120 which you multiply together to get the answer as 120. It is a two-step process for creating all the factor pairs of 120.
First, you need to list all the factors of 120. Then, you need to pair all the different combinations of these factors and it will give you all the factor pairs of 120. All factors of 120 include 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.
All of the different pair combinations from these factors of 120 are called the factor pairs of 120. Given below is the list of all the factor pairs of 120. As you can see, all the factor pairs of 120 are equal to the number 120 if you multiply them together.
- 1 x 120 = 120
- 2 x 60 = 120
- 3 x 40 = 120
- 4 x 30 = 120
- 5 x 24 = 120
- 6 x 20 = 120
- 8 x 15 = 120
- 10 x 12 = 120
- 12 x 10 = 120
- 15 x 8 = 120
- 20 x 6 = 120
- 24 x 5 = 120
- 30 x 4 = 120
- 40 x 3 = 120
- 60 x 2 = 120
- 120 x 1 = 120
The factors of 120 include the negative numbers as well since minus times minus results to plus. Hence, you can convert all the positive factor pairs simply by putting a minus sign in front of each factor, and you will get all the negative factor pairs of 120.
- -1 × -120 = 120
- -2 × -60 = 120
- -3 × -40 = 120
- -4 × -30 = 120
- -5 × -24 = 120
- -6 × -20 = 120

- -15 × -8 = 120
- -20 × -6 = 120
- -24 × -5 = 120
- -30 × -4 = 120
- -40 × -3 = 120
- -60 × -2 = 120
- -120 × -1 = 120
It is the same process as you’ve learned in the previous chapters – factors of 24 and factors of 36 in detail.
Prime Factorization of 120
To find the prime factorization of 120, we can divide the number by the smallest prime numbers (2, 3, 5, 7, …) until we get a prime number. Here’s how it works for 120:
- Divide by 2: 120÷2=60
- Divide by 2 again: 60÷2=30
- Divide by 2 once more: 30÷2=15
- Now, divide by 3: 15÷3=5
- Finally, 5 is a prime number, so we can’t divide it further.
Now, the prime factors of 120 are the prime numbers you used in the divisions: 2x2x2x3x5.
The factors of 120 are all the numbers that give the result as the number 120 when they are multiplied together in a pair of two.
