Factors of 88:
- If we have taken numbers from 1, 2, 3…for checking factors of 88, we found that 88 has factors 1, 2, 4, 8, 11, 22, 44 and 88. Hence, we must say that 88 is a composite number.
- Thus, 88 is the composite number.
- If we multiply 88 by 1, 2, 3 then we get the multiples of 88 which are 88, 176, and so on.
About the number 88:
- 88 has more than two factors which are 1,2, 4, 8, 11, 22, 44and 88 and hence it is the composite number.
- 88 is the even composite number and it is not the perfect square also.
- If we divide 88 by 1, 2, 4, 8, 11, 22, 44 and 88 then we get remainder as zero. Hence, 1, 2, 4, 8, 11, 22, 44 and 88 are the factors of 88.
Note:
- 88 is not the perfect square.
- Factors of 88: 1, 2, 4, 8, 11, 22, 44 and 88
- Prime factors of 88: 2, 11
Conclusion:
- 88 is the composite number which has factors 1, 2, 4, 8, 11, 22, 44and 88.
- And hence, 88 is not the prime number.
