# Is 1372 is a Composite number

## Is 1372 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 1372 is composite or not first we have to find its factors.

### Factors of 1372:

• If we have taken numbers from 1, 2, 3…for checking factors of 1372, we found that 1372 has factors 1, 2, 4, 7, 14, 28, 49, 98, 196, 343, 686 and 1372. Hence, we must say that 1372 is a composite number.
• Thus, 1372 is the composite number.
• If we multiply 1372 by 1, 2, 3 then we get the multiples of 1372 which are 1372, 2744 and so on.

### About the number 1372:

• 1372 has more than two factors which are 1, 2, 4, 7, 14, 28, 49, 98, 196, 343, 686 and 1372 and hence it is the composite number.
• 1372 is the even composite number and it is not the perfect square also.
• If we divide 1372 by 1, 2, 4, 7, 14, 28, 49, 98, 196, 343, 686 and 1372 then we get remainder as zero. Hence, 1, 2, 4, 7, 14, 28, 49, 98, 196, 343, 686 and 1372 are the factors of 1372.

### Note:

• 1372 is not the perfect square.
• Factors of 1372: 1, 2, 4, 7, 14, 28, 49, 98, 196, 343, 686 and 1372
• Prime factors of 1372: 2, 7

### Conclusion:

• 1372 is the composite number which has factors 1, 2, 4, 7, 14, 28, 49, 98, 196, 343, 686 and 1372
• And hence, 1372 is not the prime number.
