Factors of 3830:
- If we have taken numbers from 1, 2, 3…for checking factors of 3830, we found that 3830 has factors 1, 2, 5, 10, 383, 766, 1915 and 3830. Hence, we must say that 3830 is a composite number.
- Thus, 3830 is the composite number.
- If we multiply 3830 by 1, 2, 3 then we get the multiples of 3830 which are 3830, 7660 and so on.
About the number 3830:
- 3830 has more than two factors which are 1, 2, 5, 10, 383, 766, 1915 and 3830 and hence it is the composite number.
- 3830 is the even composite number and it is not the perfect square also.
- If we divide 3830 by, 1, 2, 5, 10, 383, 766, 1915 and 3830 then we get remainder as zero. Hence, 1, 2, 5, 10, 383, 766, 1915 and 3830 are the factors of 3830.
Note:
- 3830 is not the perfect square.
