Hi!
Let's factor these numbers to find the GCF.
48/2 = 24
24/2 = 12
12/2 = 6
6/2 = 3
3/3 = 1
2 · 2 · 2 · 2 · 3
96/2 = 48
48/2 = 24
24/2 = 12
12/2 = 6
6/2 = 3
3/3 = 1
2 · 2 · 2 · 2 · 2 · 3
The common factors that they share is 2 · 2 · 2 · 2 · 3
Multiply them and you get 48
The answer is 48.
Hope this helps! :)
