Answer:
- 12 is the GCF of 36 and 84.
Explanation:
Let's write down all of their factors.
- => 36 - 1, 2, 3, 4, 6, 9, 12, 18, 36
- => 84 - 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.
We can clearly see that both of them have the largest factor, which is 12.
Hence, 12 is the GCF of 36 and 84.
Hoped this helped.
