Question

What is the greatest common factor of 6 and 10? 2 4 6 10

Answer 1

There’s no repeating numbers so you would have to divide the middle two for 5.5

Answer 2

The correct answer is (option A)

How did we figure this out?

We are trying to find the greatest common factor of 6 and 10 so we need to divide 10 and 6:

→ 10/6

→ = 1.6

→ = 2

How does it equal 2?

Now we are rounding the number 1.6. 6 is close to 10 so it would equal 10 = 2

Therefore, the correct answer is (option A)
