Factors of 30 are numbers, which when multiplied together in pairs of two gives the result 30. We can also say that a factor is a number that divides a number completely, leaving zero as a remainder. To find the factors of 30, we will use the multiplication method here.
Factors Definition: Factors are the numbers you multiply together to get another number.
Ex: 5 x 6 = 30
5, 6 are a Factors of 30.

What are the factors of 30?
The way to find the factors of 30 is as follows:
The method of calculating the factors of 30 is as follows. First, every number is divisible by itself and 1.
| Step 1 | 1 x 30 = 30, So put them in your factor list.
1, …………. 30
| Step 2 | 2 x 15 = 30, Which means we will add them to our factor list.
1, 2 ………… 15, 30
| Step 3 | 3 x 10 = 30 not being completely divided. So we will not write 3 on the list.
1, 2, 3………..10, 15, 30
| Step 4 | 30 ÷ 4 is not being completely divided. So we will not write 4 in the list
|Step 5 | 5 x 6 = 30, Which means we will add them to our factor list.
1, 2, 3, 5 ……….6, 10, 15, 30
| Step 6 | Since we don’t have any more numbers to calculate, we are putting the numbers so far.
1, 2, 3, 5, 6, 10, 15, 30
So 1, 2, 3, 5, 6, 10, 15 and 30 are factors of 30.
Factors of (- 30)
And also -1, – 2, – 3, – 5, – 6, – 10, – 15 and – 30, because you get a positive number by multiplying two negatives, like (- 2) × (- 15) = 30.
List the factors of 30 – All the factors of 30
Here is a list of all the positive and negative factors of 30 in numerical order.
1, 2, 3, 5, 6, 10, 15, 30, -1, – 2, – 3, – 5, – 6, – 10, – 15 and – 30
What are the factor pairs for 30?
1 x 30 = 30
2 x 15 = 30
3 x 10 = 30
5 x 6 = 30
So (1, 30), (2, 15), (3, 10), (5, 6) are Pairs factors of 30.
What is the prime factorization of 30?
30 ÷ 2 = 15
15 ÷ 3 = 5
5 ÷ 5 = 1
So 2 x 3 x 5 are Prime factors of 30.
