- 1602 is the even composite number and it is not the perfect square also.
- If we divide 1602 by 1, 2, 3, 6, 9, 18, 89, 178, 267, 534, 801 and 1602 then we get remainder as zero. Hence, 1, 2, 3, 6, 9, 18, 89, 178, 267, 534, 801 and 1602 are the factors of 1602.
Note:
- 1602 is not the perfect square.
- Factors of 1602: 1, 2, 3, 6, 9, 18, 89, 178, 267, 534, 801 and 1602
- Prime factors of 1602: 2, 3, 89
Conclusion:
- 1602 is the composite number which has factors 1, 2, 3, 6, 9, 18, 89, 178, 267, 534, 801 and 1602
- And hence, 1602 is not the prime number.
