Is 50 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 50 is composite or not first we have to find its factors.

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