identify all factors of 81

To identify all the factors of 81, we need to find all the numbers that divide 81 evenly. We can start by dividing 81 by 1, which gives us 81. Then, we divide 81 by 2, 3, 4, and so on, until we reach 81. If a number divides 81 evenly, then it is a factor.

1 divides 81 evenly since 81 ÷ 1 = 81.
2 does not divide 81 evenly since 81 ÷ 2 = 40.5 (not a whole number).
3 divides 81 evenly since 81 ÷ 3 = 27.
4 does not divide 81 evenly since 81 ÷ 4 = 20.25 (not a whole number).
5 does not divide 81 evenly since 81 ÷ 5 = 16.2 (not a whole number).
And so on...

Continuing this process, we find that the factors of 81 are: 1, 3, 9, 27, and 81.

So, the factors of 81 are: 1, 3, 9, 27, and 81.
