Factors of 650:
- If we have taken numbers from 1, 2, 3…for checking factors of 650, we found that 650 has factors 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325 and 650. Hence, we must say that 650 is a composite number.
- Thus, 650 is the composite umber.
- If we multiply 650 by 1, 2, 3 then we get the multiples of 650 which are 650, 1300 and so on.
About the number 650:
- 650 has more than two factors which are 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325 and 650 and hence it is the composite number.
- 650 is the even composite number and it is not the perfect square also.
- If we divide 650 by 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325 and 650 then we get remainder as zero. Hence, 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325 and 650 are the factors of 650.
Note:
- 650 is not the perfect square.
- Factors of 650: 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325 and 650
- Prime factors of 650: 2, 5, 13
Conclusion:
- 650 is the composite number which has factors 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325 and 650
- And hence, 650 is not the prime number.
