Factors of 416:
- If we have taken numbers from 1, 2, 3…for checking factors of 416, we found that 416 has factors 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208 and 416. Hence, we must say that 416 is a composite number.
- Thus, 416 is the composite umber.
- If we multiply 416 by 1, 2, 3 then we get the multiples of 416 which are 416, 832 and so on.
About the number 416:
- 416 has more than two factors which are 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208 and 416 and hence it is the composite number.
- 416 is the even composite number and it is not the perfect square also.
- If we divide 416 by 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208 and 416 then we get remainder as zero. Hence, 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208 and 416 are the factors of 416.
Note:
- 416 is not the perfect square.
- Factors of 416: 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208 and 416
- Prime factors of 416: 2, 13
Conclusion:
- 416 is the composite number which has factors 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208
- And hence, 416 is not the prime number.
