Factors of 912:
- If we have taken numbers from 1, 2, 3…for checking factors of 912, we found that 912 has factors 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456 and 912. Hence, we must say that 912 is a composite number.
- Thus, 912 is the composite umber.
- If we multiply 912 by 1, 2, 3 then we get the multiples of 912 which are 912, 1824 and so on.
About the number 912:
- 912 has more than two factors which are 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456 and 912 and hence it is the composite number.
- 912 is the even composite number and it is not the perfect square also.
- If we divide 912 by 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456 and 912 then we get remainder as zero. Hence, 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456 and 912 are the factors of 912.
Note:
- 912 is not the perfect square.
- Factors of 912: 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456 and 912
- Prime factors of 912: 2, 3, 19
Conclusion:
- 912 is the composite number which has factors 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456 and 912
- And hence, 912 is not the prime number.
