Is 1030 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 1030 is composite or not first we have to find its factors.

Factors of 1030:
- If we have taken numbers from 1, 2, 3…for checking factors of 1030, we found that 1030 has factors 1, 2, 5, 10, 103, 206, 515 and 1030. Hence, we must say that 1030 is a composite number.
- Thus, 1030 is the composite number.
- If we multiply 1030 by 1, 2, 3 then we get the multiples of 1030 which are 1030, 2060 and so on.
About the number 1030:
- 1030 has more than two factors which are 1, 2, 5, 10, 103, 206, 515 and 1030 and hence it is the composite number.
- 1030 is the even composite number and it is not the perfect square also.
- If we divide 1030 by 1, 2, 5, 10, 103, 206, 515 and 1030 then we get remainder as zero. Hence, 1, 2, 5, 10, 103, 206, 515 and 1030 are the factors of 1030.
Note:
- 1030 is not the perfect square.
- Factors of 1030: 1, 2, 5, 10, 103, 206, 515 and 1030
- Prime factors of 1030: 2, 5, 103
Conclusion:
- 1030 is the composite number which has factors 1, 2, 5, 10, 103, 206, 515 and 1030
- And hence, 1030 is not the prime number.
