The number of decimal places in a repeating prime number must be smaller than that in the prime number itself.
Generally, decimal places with the reciprocal of prime numbers are complex. Because the reciprocal of prime numbers is also a fraction, it must be a round-robin decimal (except for 2 and 5 ), but what is the maximum

Problem DescriptionThe greatest common divisor GCD (a, B) of two positive integers a and B, sometimes written (a, B), is the largest divisor common to a and B, For example, (1, 2) = 1, (12, 18) = 6.(A, B) can be easily found by the Euclidean algorithm. Now Carp is considering a little more difficult problem:Given integers N and M, how many integer X satisfies
