Factors of 1270:
- If we have taken numbers from 1, 2, 3…for checking factors of 1270, we found that 1270 has factors 1, 2, 5, 10, 127, 254, 635 and 1270. Hence, we must say that 1270 is a composite number.
- Thus, 1270 is the composite number.
- If we multiply 1270 by 1, 2, 3 then we get the multiples of 1270 which are 1270, 2540 and so on.
About the number 1270:
- 1270 has more than two factors which are 1, 2, 5, 10, 127, 254, 635 and 1270 and hence it is the composite number.
- 1270 is the even composite number and it is not the perfect square also.
- If we divide 1270 by 1, 2, 5, 10, 127, 254, 635 and 1270 then we get remainder as zero. Hence, 1, 2, 5, 10, 127, 254, 635 and 1270 are the factors of 1270.
Note:
- 1270 is not the perfect square.
- Factors of 1270: 1, 2, 5, 10, 127, 254, 635 and 1270
- Prime factors of 1270: 2, 5, 127
Conclusion:
- 1270 is the composite number which has factors 1, 2, 5, 10, 127, 254, 635 and 1270
- And hence, 1270 is not the prime number.
