Factors of 572:
- If we have taken numbers from 1, 2, 3…for checking factors of 572, we found that 572 has factors 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286 and 572. Hence, we must say that 572 is a composite number.
- Thus, 572 is the composite umber.
- If we multiply 572 by 1, 2, 3 then we get the multiples of 572 which are 572, 1144 and so on.
About the number 572:
- 572 has more than two factors which are 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286 and 572 and hence it is the composite number.
- 572 is the even composite number and it is not the perfect square also.
- If we divide 572 by 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286 and 572 then we get remainder as zero. Hence, 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286 and 572 are the factors of 572.
Note:
- 572 is not the perfect square.
- Factors of 572: 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286 and 572
- Prime factors of 572: 2, 11, 13
Conclusion:
- 572 is the composite number which has factors 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286 and 572
- And hence, 572 is not the prime number.
