Answer:
1. 6
2. 5
3. 8
Step-by-step explanation:
You can find the GCF thru factoring. The prime factors of 12 and 30 are 2 and 3, and if you multiply those two numbers, you get six. The only prime factor between 20 and 35 is 5. And for 16 and 40, there are three common number 2's. Multiplying those twos gives you 8.
