__Is 160 is a composite number or not ?__

- As we already know that, the number having factors 1 and the number itself is the prime number.
- And numbers having more than these two factors are the composite numbers.
- To check whether the number 160 is composite or not first we have to find its factors.

**Factors of 160:**

- If we have taken numbers from 1, 2, 3…for checking factors of 160, we found that 160 has factors 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80 and 160. Hence, we must say that 160 is a composite number.
- Thus, 160 is the composite number.
- If we multiply 160 by 1, 2, 3 then we get the multiples of 160 which are 160, 320, and so on.

__About the number 160:__

__About the number 160:__

- 160 has more than two factors which are 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80 and 160 and hence it is the composite number.
- 160 is the even composite number and it is not the perfect square also.
- If we divide 160 by 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80 and 160 then we get remainder as zero. Hence, 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80 and 160 are the factors of 160.

__Note:__

__Note:__

- 160 is not the perfect square.
- Factors of 160: 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80 and 160
- Prime factors of 160: 2, 5

**Conclusion:**

- 160 is the composite number which has factors 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80 and 160.
- And hence, 160 is not the prime number.
