What are the Factors of 18?

The following are the different types of factors of 18:

• Factors of 18: 1, 2, 3, 6, 9, 18

• Negative Factors of 18: -1, -2, -3, -6, -9, -18

• Prime Factors of 18: 2, 3

• Prime Factorization of 18: $2^1\times3^2$

Factors by Division Method

To calculate the factors of 18, start by dividing the numbers by the smallest prime number, which is 2. If the number is not divisible by 2, proceed to the next prime number, such as 3, 5, 7, 11, 13, and continue this process until you reach 1.

Step 1: 18 ÷ 2 = 9
Step 2: 9 ÷ 3 = 3
Step 3: 3 ÷ 3 = 1

In step 3, we have reached to 1, and so, the process is stopped.

• Prime Factors of 18: $2\times3\times3$

• Prime Factorization of 18: $2^1\times3^2$

The factors will be all the multiples of 1, 2, 3, 3, 9, 18

Calculating all the factors:
2 = 1 x 2
3 = 1 x 3
6 = 1 x 2 x 3
9 = 1 x 9
18 = 1 x 18

Finally Factors of 18 = 1, 2, 3, 6, 9, 18
