- 3650 has more than two factors which are 1, 2, 5, 10, 25, 50, 73, 146, 365, 730, 1825 and 3650 and hence it is the composite number.
- 3650 is the even composite number and it is not the perfect square also.
- If we divide 3650 by, 1, 2, 5, 10, 25, 50, 73, 146, 365, 730, 1825 and 3650 then we get remainder as zero. Hence, 1, 2, 5, 10, 25, 50, 73, 146, 365, 730, 1825 and 3650 are the factors of 3650.
Note:
- 3650 is not the perfect square.
- Factors of 3650: 1, 2, 5, 10, 25, 50, 73, 146, 365, 730, 1825 and 3650
- Prime factors of 3650: 2, 5, 73
Conclusion:
- 3650 is the composite number which has factors, 1, 2, 5, 10, 25, 50, 73, 146, 365, 730, 1825 and 3650
- And hence, 3650 is not the prime number.
