Is 1250 is a composite number or not ?
- As we already know that, the number having factors 1 and the number itself is the prime number.
- And numbers having more than these two factors are the composite numbers.
- To check whether the number 1250 is composite or not first we have to find its factors.

Factors of 1250:
- If we have taken numbers from 1, 2, 3…for checking factors of 1250, we found that 1250 has factors 1, 2, 5, 10, 25, 50, 125, 250, 625 and 1250. Hence, we must say that 1250 is a composite number.
- Thus, 1250 is the composite number.
- If we multiply 1250 by 1, 2, 3 then we get the multiples of 1250 which are 1250, 2500 and so on.
About the number 1250:
- 1250 has more than two factors which are 1, 2, 5, 10, 25, 50, 125, 250, 625 and 1250 and hence it is the composite number.
- 1250 is the even composite number and it is not the perfect square also.
- If we divide 1250 by 1, 2, 5, 10, 25, 50, 125, 250, 625 and 1250 then we get remainder as zero. Hence, 1, 2, 5, 10, 25, 50, 125, 250, 625 and 1250 are the factors of 1250.
Note:
- 1250 is not the perfect square.
- Factors of 1250: 1, 2, 5, 10, 25, 50, 125, 250, 625 and 1250
- Prime factors of 1250: 2, 5
Conclusion:
- 1250 is the composite number which has factors 1, 2, 5, 10, 25, 50, 125, 250, 625 and 1250
- And hence, 1250 is not the prime number.
