Factors of 702:
- If we have taken numbers from 1, 2, 3…for checking factors of 702, we found that 702 has factors 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351 and 702. Hence, we must say that 702 is a composite number.
- Thus, 702 is the composite umber.
- If we multiply 702 by 1, 2, 3 then we get the multiples of 702 which are 702, 1404 and so on.
About the number 702:
- 702 has more than two factors which are 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351 and 702 and hence it is the composite number.
- 702 is the even composite number and it is not the perfect square also.
- If we divide 702 by 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351 and 702 then we get remainder as zero. Hence, 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351 and 702 are the factors of 702.

- 702 is not the perfect square.
- Factors of 702: 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351 and 702
- Prime factors of 702: 2, 3, 13
Conclusion:
- 702 is the composite number which has factors 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351 and 702
- And hence, 702 is not the prime number.
