Is 3790 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 3790 is composite or not first we have to find its factors.
Factors of 3790:
- If we have taken numbers from 1, 2, 3…for checking factors of 3790, we found that 3790 has factors 1, 2, 5, 10, 379, 758, 1895 and 3790. Hence, we must say that 3790 is a composite number.
- Thus, 3790 is the composite number.
- If we multiply 3790 by 1, 2, 3 then we get the multiples of 3790 which are 3790, 7580 and so on.
About the number 3790:
- 3790 has more than two factors which are 1, 2, 5, 10, 379, 758, 1895 and 3790 and hence it is the composite number.
- 3790 is the even composite number and it is not the perfect square also.
- If we divide 3790 by, 1, 2, 5, 10, 379, 758, 1895 and 3790 then we get remainder as zero. Hence, 1, 2, 5, 10, 379, 758, 1895 and 3790 are the factors of 3790.
Note:
- 3790 is not the perfect square.
- Factors of 3790: 1, 2, 5, 10, 379, 758, 1895 and 3790
- Prime factors of 3790: 2, 5, 379
Conclusion:
- 3790 is the composite number which has factors, 1, 2, 5, 10, 379, 758, 1895 and 3790
- And hence, 3790 is not the prime number.
