Factors of 2630:
- If we have taken numbers from 1, 2, 3…for checking factors of 2630, we found that 2630 has factors 1, 2, 5, 10, 263, 526, 1315 and 2630. Hence, we must say that 2630 is a composite number.
- Thus, 2630 is the composite number.
- If we multiply 2630 by 1, 2, 3 then we get the multiples of 2630 which are 2630, 5260 and so on.
About the number 2630:
- 2630 has more than two factors which are 1, 2, 5, 10, 263, 526, 1315 and 2630 and hence it is the composite number.
- 2630 is the even composite number and it is not the perfect square also.
- If we divide 2630 by, 1, 2, 5, 10, 263, 526, 1315 and 2630 then we get remainder as zero. Hence, 1, 2, 5, 10, 263, 526, 1315 and 2630 are the factors of 2630.
Note:
- 2630 is not the perfect square.
- Factors of 2630: 1, 2, 5, 10, 263, 526, 1315 and 2630
- Prime factors of 2630: 2, 5, 263
Conclusion:
- 2630 is the composite number which has factors, 1, 2, 5, 10, 263, 526, 1315 and 2630
- And hence, 2630 is not the prime number.
