the lcm is 30 the gcf is 2 whats the pair of numbers for each set of conditions

Answer 1

lcm(x,y) = x y/gcf(x,y) --------->

x y = 60 = 2*2*15

So, we can take x = 2 and y = 30.

Answer 2

thats sooooooo wrong

Answer 3

30 is the least common multiple of:

1, 30
2, 15
3, 10
5, 6

However, 2 is not the greatest common factor of any of those pairs.
