Cyclicity of 19

Here we will show you how to find the Cyclicity of 19. First you make the following calculations:

19¹ = 19
19² = 361
19³ = 6859
19⁴ = 130321
19⁵ = 2476099

Then you look at the last digit of each of the numbers you found above: 9 1 9 1 9.

The Cyclicity of any number such as 19 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 19.

As you can see, the Cyclicity of 19 has 2 different numbers. The Cyclicity of 19 is
