Factors of 1810:
- If we have taken numbers from 1, 2, 3…for checking factors of 1810, we found that 1810 has factors 1, 2, 5, 10, 181, 362, 905 and 1810. Hence, we must say that 1810 is a composite number.
- Thus, 1810 is the composite number.
- If we multiply 1810 by 1, 2, 3 then we get the multiples of 1810 which are 1810, 3620 and so on.
About the number 1810:
- 1810 has more than two factors which are 1, 2, 5, 10, 181, 362, 905 and 1810 and hence it is the composite number.
- 1810 is the even composite number and it is not the perfect square also.
- If we divide 1810 by, 1, 2, 5, 10, 181, 362, 905 and 1810 then we get remainder as zero. Hence, 1, 2, 5, 10, 181, 362, 905 and 1810 are the factors of 1810.
Note:
- 1810 is not the perfect square.
- Factors of 1810: 1, 2, 5, 10, 181, 362, 905 and 1810
- Prime factors of 1810: 2, 5, 181
Conclusion:
- 1810 is the composite number which has factors 1, 2, 5, 10, 181, 362, 905 and 1810
- And hence, 1810 is not the prime number.
