Answer:
Hello!
To answer these, you can use prime factorization! Here is the first one:
1) 16x² and 8
Well we know the GCF will not have any "x" since only one of the numbers do. So, here is the prime factorization for each, excluding the "x", and I have also bolded the common numbers between the two:
16 8
2 · 8 2 · 4
2 · 4 2 · 2
2 · 2
Finally, multiply the common numbers (only once for each common number): 2 x 2 x 2= 8 is your GCF!!!
Hope this helps! :)
