Factors of 4210:
- If we have taken numbers from 1, 2, 3…for checking factors of 4210 we found that 4210 has factors 1, 2, 5, 10, 421, 842, 2105 and 4210. Hence, we must say that 4210 is a composite number.
- Thus, 4210 is the composite number.
- If we multiply 4210 by 1, 2, 3 then we get the multiples of 4210 which are 4210, 8420 and so on.
About the number 4210:
- 4210 has more than two factors which are 1, 2, 5, 10, 421, 842, 2105 and 4210 and hence it is the composite number.
- 4210 is the even composite number and it is not the perfect square also.
- If we divide 4210 by, 1, 2, 5, 10, 421, 842, 2105 and 4210 then we get remainder as zero. Hence, 1, 2, 5, 10, 421, 842, 2105 and 4210 are the factors of 4210.
Note:
- 4210 is not the perfect square.
- Factors of 4210: 1, 2, 5, 10, 421, 842, 2105 and 4210
- Prime factors of 4210: 2, 5, 421
