Factors of 1850:
- If we have taken numbers from 1, 2, 3…for checking factors of 1850, we found that 1850 has factors 1, 2, 5, 10, 25, 37, 50, 74, 185, 370, 925 and 1850. Hence, we must say that 1850 is a composite number.
- Thus, 1850 is the composite number.
- If we multiply 1850 by 1, 2, 3 then we get the multiples of 1850 which are 1850, 3700 and so on.
About the number 1850:
- 1850 has more than two factors which are 1, 2, 5, 10, 25, 37, 50, 74, 185, 370, 925 and 1850 and hence it is the composite number.
- 1850 is the even composite number and it is not the perfect square also.
- If we divide 1850 by, 1, 2, 5, 10, 25, 37, 50, 74, 185, 370, 925 and 1850 then we get remainder as zero. Hence, 1, 2, 5, 10, 25, 37, 50, 74, 185, 370, 925 and 1850 are the factors of 1850.
Note:
- 1850 is not the perfect square.
- Factors of 1850: 1, 2, 5, 10, 25, 37, 50, 74, 185, 370, 925 and 1850
- Prime factors of 1850: 2, 5, 37
Conclusion:
- 1850 is the composite number which has factors 1, 2, 5, 10, 25, 37, 50, 74, 185, 370, 925 and 1850
- And hence, 1850 is not the prime number.
