- And numbers having more than these two factors are the composite numbers.
- To check whether the number 662 is composite or not first we have to find its factors.
Factors of 662:
- If we have taken numbers from 1, 2, 3…for checking factors of 662, we found that 662 has factors 1, 2, 331 and 662. Hence, we must say that 662 is a composite number.
- Thus, 662 is the composite umber.
- If we multiply 662 by 1, 2, 3 then we get the multiples of 662 which are 662, 1324 and so on.
About the number 662:
- 662 has more than two factors which are 1, 2, 331 and 662 and hence it is the composite number.
- 662 is the even composite number and it is not the perfect square also.
- If we divide 662 by 1, 2, 331 and 662 then we get remainder as zero. Hence, 1, 2, 331 and 662 are the factors of 662.
Note:
- 662 is not the perfect square.
- Factors of 662: 1, 2, 331 and 662
