Factors of 1630:
- If we have taken numbers from 1, 2, 3…for checking factors of 1630, we found that 1630 has factors 1, 2, 5, 10, 163, 326, 815 and 1630. Hence, we must say that 1630 is a composite number.
- Thus, 1630 is the composite number.
- If we multiply 1630 by 1, 2, 3 then we get the multiples of 1630 which are 1630, 3260 and so on.
About the number 1630:
- 1630 has more than two factors which are 1, 2, 5, 10, 163, 326, 815 and 1630 and hence it is the composite number.
- 1630 is the even composite number and it is not the perfect square also.
- If we divide 1630 by 1, 2, 5, 10, 163, 326, 815 and 1630 then we get remainder as zero. Hence, 1, 2, 5, 10, 163, 326, 815 and 1630 are the factors of 1630.
Note:
- 1630 is not the perfect square.
- Factors of 1630: 1, 2, 5, 10, 163, 326, 815 and 1630
- Prime factors of 1630: 2, 5, 163
