Step-by-step explanation:

Remark

I take it that 24 is in front of j which means that the term is 24j. There shouldn't be a comma there.

24 = 8*3
16 = 8*2

Both numbers have 8 in common, and that's all they have in common. The GCF is therefore, 8

24j - 16 = 8(3j - 2) That's the answer.

Answer: 8 (3j - 2)
