Prime numbers have always been discussed a lot. Some mathematicians have tried to study the reason of the order they follow, without reaching any conclusion. Here we try to make an exhaustive study of prime numbers up to 2,000,000, counting the percentages of the number of appearances of each last digit.

For that, we have calculated all prime numbers up to 2,000,000 (148,933 numbers) and the percentages that end in 1, 3, 7, 9 (apart from those there are 2 and 5).
