Factors of 1370:
- If we have taken numbers from 1, 2, 3…for checking factors of 1370, we found that 1370 has factors 1, 2, 5, 10, 137, 274, 685 and 1370. Hence, we must say that 1370 is a composite number.
- Thus, 1370 is the composite number.
- If we multiply 1370 by 1, 2, 3 then we get the multiples of 1370 which are 1370, 2740 and so on.
About the number 1370:
- 1370 has more than two factors which are 1, 2, 5, 10, 137, 274, 685 and 1370 and hence it is the composite number.
- 1370 is the even composite number and it is not the perfect square also.
- If we divide 1370 by 1, 2, 5, 10, 137, 274, 685 and 1370 then we get remainder as zero. Hence, 1, 2, 5, 10, 137, 274, 685 and 1370 are the factors of 1370.
Note:
- 1370 is not the perfect square.
- Factors of 1370: 1, 2, 5, 10, 137, 274, 685 and 1370
- Prime factors of 1370: 2, 5, 137
Conclusion:
- 1370 is the composite number which has factors 1, 2, 5, 10, 137, 274, 685 and 1370
- And hence, 1370 is not the prime number.
