Factors of 1206:
- If we have taken numbers from 1, 2, 3…for checking factors of 1206, we found that 1206 has factors 1, 2, 3, 6, 9, 18, 67, 134, 201, 402, 603 and 1206. Hence, we must say that 1206 is a composite number.
- Thus, 1206 is the composite number.
- If we multiply 1206 by 1, 2, 3 then we get the multiples of 1206 which are 1206, 2412 and so on.
About the number 1206:
- 1206 has more than two factors which are 1, 2, 3, 6, 9, 18, 67, 134, 201, 402, 603 and 1206 and hence it is the composite number.
- 1206 is the even composite number and it is not the perfect square also.
- If we divide 1206 by 1, 2, 3, 6, 9, 18, 67, 134, 201, 402, 603 and 1206 then we get remainder as zero. Hence, 1, 2, 3, 6, 9, 18, 67, 134, 201, 402, 603 and 1206 are the factors of 1206.
Note:
- 1206 is not the perfect square.
- Factors of 1206: 1, 2, 3, 6, 9, 18, 67, 134, 201, 402, 603 and 1206
- Prime factors of 1206: 2, 3, 67
Conclusion:
- 1206 is the composite number which has factors 1, 2, 3, 6, 9, 18, 67, 134, 201, 402, 603 and 1206
- And hence, 1206 is not the prime number.
