Cyclicity of 21

Here we will show you how to find the Cyclicity of 21. First you make the following calculations:

21¹ = 21
21² = 441
21³ = 9261
21⁴ = 194481
21⁵ = 4084101

Then you look at the last digit of each of the numbers you found above: 1 1 1 1 1.

The Cyclicity of any number such as 21 is a sequence of 1 to 4 numbers. You will see that the last digits from the answers above will start repeating themselves. This sequence of numbers that repeats itself is called the Cyclicity of 21.

As you can see, the Cyclicity of 21 has 1 number. The Cyclicity of 21 is
