Factors of 550:
- If we have taken numbers from 1, 2, 3…for checking factors of 550, we found that 550 has factors 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275 and 550. Hence, we must say that 550 is a composite number.
- Thus, 550 is the composite umber.
- If we multiply 550 by 1, 2, 3 then we get the multiples of 550 which are 550, 1100 and so on.
About the number 550:
- 550 has more than two factors which are 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275 and 550 and hence it is the composite number.
- 550 is the even composite number and it is not the perfect square also.
- If we divide 550 by 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275 and 550 then we get remainder as zero. Hence, 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275 and 550 are the factors of 550.
Note:
- 550 is not the perfect square.
- Factors of 550: 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275 and 550
- Prime factors of 550: 2, 5, 11
Conclusion:
- 550 is the composite number which has factors 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275 and 550
- And hence, 550 is not the prime number.
