Factors of 940:
- If we have taken numbers from 1, 2, 3…for checking factors of 940, we found that 940 has factors 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470 and 940. Hence, we must say that 940 is a composite number.
- Thus, 940 is the composite umber.
- If we multiply 940 by 1, 2, 3 then we get the multiples of 940 which are 940, 1880 and so on.
About the number 940:
- 940 has more than two factors which are 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470 and 940 and hence it is the composite number.
- 940 is the even composite number and it is not the perfect square also.
- If we divide 940 by 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470 and 940 then we get remainder as zero. Hence, 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470 and 940 are the factors of 940.
Note:
- 940 is not the perfect square.
- Factors of 940: 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470 and 940
- Prime factors of 940: 2, 5, 47
Conclusion:
- 940 is the composite number which has factors 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470 and 940
- And hence, 940 is not the prime number.
