Factors of 250:
- If we have taken numbers from 1, 2, 3…for checking factors of 250, we found that 250 has factors 1, 2, 5, 10, 25, 50, 125 and 250. Hence, we must say that 250 is a composite number.
- Thus, 250 is the composite umber.
- If we multiply 250 by 1, 2, 3 then we get the multiples of 250 which are 250, 500, and so on
About the number 250:
- 250 has more than two factors which are 1, 2, 5, 10, 25, 50, 125 and 250 and hence it is the composite number.
- 250 is the even composite number and it is not the perfect square also.
- If we divide 250 by 1, 2, 5, 10, 25, 50, 125 and 250 then we get remainder as zero. Hence, 1, 2, 5, 10, 25, 50, 125 and 250 are the factors of 250.
Note:
- 250 is not the perfect square.
- Factors of 250: 1, 2, 5, 10, 25, 50, 125 and 250
- Prime factors of 250: 2, 5
Conclusion:
- 250 is the composite number which has factors 1, 2, 5, 10, 25, 50, 125 and 250.
- And hence, 250 is not the prime number.
