Factors of 910:
- If we have taken numbers from 1, 2, 3…for checking factors of 910, we found that 910 has factors 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455 and 910. Hence, we must say that 910 is a composite number.
- Thus, 910 is the composite umber.
- If we multiply 910 by 1, 2, 3 then we get the multiples of 910 which are 910, 1820 and so on.
About the number 910:
- 910 has more than two factors which are 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455 and 910 and hence it is the composite number.
- 910 is the even composite number and it is not the perfect square also.
- If we divide 910 by 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455 and 910 then we get remainder as zero. Hence, 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455 and 910 are the factors of 910.
Note:
- 910 is not the perfect square.
- Factors of 910: 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455 and 910
- Prime factors of 910: 2, 5, 7, 13
Conclusion:
- 910 is the composite number which has factors 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455 and 910
- And hence, 910 is not the prime number.
