Is 500 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 500 is composite or not first we have to find its factors.

Factors of 500:
- If we have taken numbers from 1, 2, 3…for checking factors of 500, we found that 500 has factors 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250 and 500. Hence, we must say that 500 is a composite number.
- Thus, 500 is the composite umber.
- If we multiply 500 by 1, 2, 3 then we get the multiples of 500 which are 500, 1000 and so on.
About the number 500:
- 500 has more than two factors which are 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250 and 500 and hence it is the composite number.
- 500 is the even composite number and it is not the perfect square also.
- If we divide 500 by 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250 and 500 then we get remainder as zero. Hence, 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250 and 500 are the factors of 500.
Note:
- 500 is not the perfect square.
- Factors of 500:1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250 and 500
- Prime factors of 500: 2, 5
Conclusion:
- 500 is the composite number which has factors 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250 and 500
- And hence, 500 is not the prime number.
