Factors of 928:
- If we have taken numbers from 1, 2, 3…for checking factors of 928, we found that 928 has factors 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464 and 928. Hence, we must say that 928 is a composite number.
- Thus, 928 is the composite umber.
- If we multiply 928 by 1, 2, 3 then we get the multiples of 928 which are 928, 1856 and so on.
About the number 928:
- 928 has more than two factors which are 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464 and 928 and hence it is the composite number.
- 928 is the even composite number and it is not the perfect square also.
- If we divide 928 by 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464 and 928 then we get remainder as zero. Hence, 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464 and 928 are the factors of 928.
Note:
- 928 is not the perfect square.
- Factors of 928: 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464 and 928
- Prime factors of 928: 2, 29
Conclusion:
- 928 is the composite number which has factors 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464 and 928
- And hence, 928 is not the prime number.
