Factors of 207:
- If we have taken numbers from 1, 2, 3…for checking factors of 207, we found that 207 has factors 1, 3, 9, 23, 69 and 207. Hence, we must say that 207 is a composite number.
- Thus, 207 is the composite number.
- If we multiply 207 by 1, 2, 3 then we get the multiples of 207 which are 207, 414, and so on.
About the number 207:
- 207 has more than two factors which are 1, 3, 9, 23, 69 and 207 and hence it is the composite number.
- 207 is the odd composite number and it is not the perfect square also.
- If we divide 207 by 1, 3, 9, 23, 69 and 207 then we get remainder as zero. Hence, 1, 3, 9, 23, 69 and 207 are the factors of 207.
Note:
- 207 is not the perfect square.
- Factors of 207: 1, 3, 9, 23, 69 and 207
- Prime factors of 207: 3, 23
Conclusion:
- 207 is the composite number which has factors 1, 3, 9, 23, 69 and 207.
- And hence, 207 is not the prime number.
