Factors of 404:
- If we have taken numbers from 1, 2, 3…for checking factors of 404, we found that 404 has factors 1, 2, 4, 101, 202 and 404. Hence, we must say that 404 is a composite number.
- Thus, 404 is the composite umber.
- If we multiply 404 by 1, 2, 3 then we get the multiples of 404 which are 404, 808 and so on.
About the number 404:
- 404 has more than two factors which are 1, 2, 4, 101, 202 and 404 and hence it is the composite number.
- 404 is the even composite number and it is not the perfect square also.
- If we divide 404 by 1, 2, 4, 101, 202 and 404 then we get remainder as zero. Hence, 1, 2, 4, 101, 202 and 404 are the factors of 404.
Note:
- 404 is not the perfect square.
- Factors of 404: 1, 2, 4, 101, 202 and 404
- Prime factors of 404: 2, 101
Conclusion:
- 404 is the composite number which has factors 1, 2, 4, 101, 202 and 404
- And hence, 404 is not the prime number.
