    91=13*7

    since 91 can be divide in to 13 and 7

    so the samllest of m should be able to divide by 13

    the smallest value that can divide into 13 is 13

    so the smallest of M is 13

    22=2*11

    since 22 could be divided by 2 and 11

    so the largest of n should be able to divide 11 and 2

    since 2 had already appeared

    so n=11
