2 and 40, for example.
91
They are: 3*49 = 147
21 and 7, 3 and 49, 147 and 1
(49,3)(21,7)
The least common multiple of these two numbers is 147.
There are infinitely many answers. Two examples: 1*147 10*14.7
1 x 84 2 x 42 3 x 28 4 x 21 6 x 14 7 x 12
147,1 49,3 21,7
3 and 49
I got 3X49
1 x 147, 3 x 49, 7 x 21
