Yes, 360 \( \div\) 12 = 30

Remainder = 0

12 x 30 = 360

13

No, 360 \( \div\) 13 = 27

Remainder = 9

-

14

No, 360 \( \div\) 14 = 25

Remainder = 10

-

15

Yes, 360 \( \div\) 15 = 24

Remainder = 0

15 x 24 = 360

16

No, 360 \( \div\) 16 = 22

Remainder = 8

-

17

No, 360 \( \div\) 17 = 21

Remainder = 3

-

18

Yes, 360 \( \div\) 18 = 20

Remainder = 0

18 x 20 = 360

19

No, 360 \( \div\) 19 = 18

Remainder = 18

-

20

Yes, 360 \( \div\) 20 = 3

Remainder = 0

20 x 18 = 360

As we can observe in the table, as we progress beyond the division and multiplication operations of the number 20, the factor pairs will start to repeat. Hence, we can conclude here, and say that the factors of 360 are, 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360.

Prime Factors of 360

By applying the factor tree method it’s convenient to list the prime factors of 360.

Solved Factors of 360 Examples

Example 1: 

Charlie and Shawn visited a restaurant. The food they had cost them $360. How much did Shawn pay if Charlie paid $90? Was the sum each of them paid a factor of 360?

 

Solution:

As mentioned, the total amount paid by both Shawn and Charlie was $360.

If Charlie paid $90, then, the amount paid by Shawn would be,

$360 – $90 = $270

 

Hence, Shawn needs to pay $270.

360 \(\div\) 90 = 4 R0

360 \(\div\) 270 = 1 R90

So, 90 is a factor of 360, but 270 is not a factor of 360.

 

Example 2:

What is the greatest common factor of the numbers 360 and 400?

 

Solution:

The factors of 400 are: 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200 and 400.

And the factors of 360 are: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180 and 360.

From the list of factors, the greatest common factor of 360 and 400 is 40.

 

Example 3: 

What would be the product of prime factors of the number 360?

 

Solution:

As we know, the prime factors of 360 are 2, 3 and 5

2 × 3 × 5

30

Hence, the product of prime factors of 360 is 30.

Frequently Asked Questions on Factors of 360

Since the prime factors of 360 are 2³×3²×5, two appears three times in the prime factorization of 360.

The factors of 360 are 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 72, 90, 120, 180, 360. 

Adding all these factors together, the sum is,
