Factors of 604:
- If we have taken numbers from 1, 2, 3…for checking factors of 604, we found that 604 has factors 1, 2, 4, 151, 302 and 604. Hence, we must say that 604 is a composite number.
- Thus, 604 is the composite umber.
- If we multiply 604 by 1, 2, 3 then we get the multiples of 604 which are 604, 1208 and so on.
About the number 604:
- 604 has more than two factors which are 1, 2, 4, 151, 302 and 604 and hence it is the composite number.
- 604 is the even composite number and it is not the perfect square also.
- If we divide 604 by 1, 2, 4, 151, 302 and 604 then we get remainder as zero. Hence, 1, 2, 4, 151, 302 and 604 are the factors of 604.
