    Easy

    Given two positive integers a and b, return the number of common factors of a and b.

    An integer x is a common factor of a and b if x divides both a and b.

    Example 1:

    Input: a = 12, b = 6

    Output: 4

    Explanation: The common factors of 12 and 6 are 1, 2, 3, 6.

    Example 2:

    Input: a = 25, b = 30

    Output: 2

    Explanation: The common factors of 25 and 30 are 1, 5.
