Factors of 608:
- If we have taken numbers from 1, 2, 3…for checking factors of 608, we found that 608 has factors 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304 and 608. Hence, we must say that 608 is a composite number.
- Thus, 608 is the composite umber.
- If we multiply 608 by 1, 2, 3 then we get the multiples of 608 which are 608, 1216 and so on.
About the number 608:
- 608 has more than two factors which are 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304 and 608 and hence it is the composite number.
- 608 is the even composite number and it is not the perfect square also.
- If we divide 608 by 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304 and 608 then we get remainder as zero. Hence, 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304 and 608 are the factors of 608.
Note:
- 608 is not the perfect square.
- Factors of 608: 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304 and 608
- Prime factors of 608: 2, 19
Conclusion:
- 608 is the composite number which has factors 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304 and 608
- And hence, 608 is not the prime number.
