Cyclicity of 645

Here we will show you how to find the Cyclicity of 645. First you make the following calculations:

645¹ = 645
645² = 416025
645³ = 268336125
645⁴ = 173076800625
645⁵ = 111634536403125

Then you look at the last digit of each of the numbers you found above: 5 5 5 5 5.

The Cyclicity of any number such as 645 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 645.

As you can see, the Cyclicity of 645 has 1 number. The Cyclicity of 645 is
