For common factor, you need to factorise completely for the numbers. So lets say,
36 and 24.
24: 2X2X2X3
36: 2X2X3X3
you realise that both 24 and 36 have at least two 2s and one 3.
Gcf: 2,2,3 multiply all of them and you get 12

Yep but youll have to factorise fully to the smallest like 9 will be 3X3

Ah... Greatest common factor and lowest common multiple...
You will need to factorise the number into its base factors first. For example take 20 and 28.
28: 2X2X7
20: 2X2X5
Common factors are: 2X2
So the highest common factor is 4.
So the lowest common multiple is gotten by multiplying each other with the factor which they dont have.
2X2X5X7= 140
