Factors of 801:
- If we have taken numbers from 1, 2, 3…for checking factors of 801, we found that 801 has factors 1, 3, 9, 89, 267 and 801. Hence, we must say that 801 is a composite number.
- Thus, 801 is the composite number.
- If we multiply 801 by 1, 2, 3 then we get the multiples of 801 which are 801, 1602 and so on.
801 is a Composite number or Prime number
About the number 801:
- 801 has more than two factors which are 1, 3, 9, 89, 267 and 801 and hence it is the composite number.
- 801 is the odd composite number and it is not the perfect square also.
- If we divide 801 by 1, 3, 9, 89, 267 and 801 then we get remainder as zero. Hence, 1, 3, 9, 89, 267 and 801 are the factors of 801
