Factors of 1180:
- If we have taken numbers from 1, 2, 3…for checking factors of 1180, we found that 1180 has factors 1, 2, 4, 5, 10, 20, 59, 118, 236, 295, 590 and 1180. Hence, we must say that 1180 is a composite number.
- Thus, 1180 is the composite number.
- If we multiply 1180 by 1, 2, 3 then we get the multiples of 1180 which are 1180, 2360 and so on.
About the number 1180:
- 1180 has more than two factors which are 1, 2, 4, 5, 10, 20, 59, 118, 236, 295, 590 and 1180 and hence it is the composite number.
- 1180 is the even composite number and it is not the perfect square also.
- If we divide 1180 by 1, 2, 4, 5, 10, 20, 59, 118, 236, 295, 590 and 1180 then we get remainder as zero. Hence, 1, 2, 4, 5, 10, 20, 59, 118, 236, 295, 590 and 1180 are the factors of 1180.
Note:
- 1180 is not the perfect square.
- Factors of 1180: 1, 2, 4, 5, 10, 20, 59, 118, 236, 295, 590 and 1180
- Prime factors of 1180: 2, 5, 59
Conclusion:
- 1180 is the composite number which has factors 1, 2, 4, 5, 10, 20, 59, 118, 236, 295, 590 and 1180
- And hence, 1180 is not the prime number.
