Is 132 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 132 is composite or not first we have to find its factors.

Factors of 132:
- If we have taken numbers from 1, 2, 3…for checking factors of 132, we found that 132 has factors 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66 and 132. Hence, we must say that 132 is a composite number.
- Thus, 132 is the composite number.
- If we multiply 132 by 1, 2, 3 then we get the multiples of 132 which are 132, 264, and so on.
About the number 132:
- 132 has more than two factors which are 1,2, 3, 4, 6, 11, 12, 22, 33, 44, 66and132 and hence it is the composite number.
- 132 is the even composite number and it is not the perfect square also.
- If we divide 132 by 1,2, 3, 4, 6, 11, 12, 22, 33, 44, 66 and132 then we get remainder as zero. Hence, 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66and 132 are the factors of 132.
Note:
- 132 is not the perfect square.
- Factors of 132: 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66 and 132
- Prime factors of 132: 2, 3, 11
Conclusion:
- 132 is the composite number which has factors 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66 and 132.
- And hence, 132 is not the prime number.
