All prime numbers have exactly two factors. There is not a prime number below 50 that has the most factors since they all have the same number of factors.
That would depend upon the other number(s) with which the factors are common.The factors of 50 are 1, 2, 5, 10, 25 & 50, so the common factors of 50 will be 1 or more of these dependent upon the other number(s).For example:The common factor of 50 and 3 is: 1The common factors of 50 and 10 are: 1, 2, 5, 10The common factors of 50 and 25 are: 1, 5, 25The common factors of 50 and 210 are 1, 2, 5, 10
