Factors of 502:
- If we have taken numbers from 1, 2, 3…for checking factors of 502, we found that 502 has factors 1, 2, 251 and 502. Hence, we must say that 502 is a composite number.
- Thus, 502 is the composite umber.
- If we multiply 502 by 1, 2, 3 then we get the multiples of 502 which are 502, 1004
- and so on.
About the number 502:
- 502 has more than two factors which are 1, 2, 251 and 502 and hence it is the composite number.
- 502 is the even composite number and it is not the perfect square also.
- If we divide 502 by 1, 2, 251 and 502 then we get remainder as zero. Hence, 1, 2, 251 and 502 are the factors of 502.
Note:
- 502 is not the perfect square.
- Factors of 502:1, 2, 251 and 502
- Prime factors of 502: 2, 251
Conclusion:
- 502 is the composite number which has factors 1, 2, 251 and 502
- And hence, 502 is not the prime number.
