Let the gcd be t
the 2 numbers are at and bt with a < b where a and b are coprimes or a =1
Therefore, the LCM = abt
so abt + t = 111 or 111 = t(1+ab) = 3 * 37
then we have following cases
t = 1 , ab = 110 then a = 1, b= 110 giving 2 numbers 1 and 110
a = 2, b= 55 giving 2 numbers 2 and 55
or a = 5 , b = 22 giving 2 numbers 5 and 22
or a = 10, b = 11 giving 2 numbers 10 and 11
t=3, ab = 36 then a = 1, b= 36 giving 2 numbers 3 and 108
a = 4, b= 9 giving 2 numbers 12 and 27
t = 37, ab =2 then a = 1, b=2 giving 37 and 74
