Answer:
45(1 + 2)
Explanation:
To find the greatest common factor, we find the multiples of 45 and 90.
45: 1, 3, 5, 9, 15, 45
90: 1, 2, 3, 5, 6, 9, 15, 18, 45...
The easier way to do this is divide 90 by 2 to get our GCF, 45.
We place the 45 (GCF) in the first box and we place 1 and 2 in the parentheses because when you distribute, we get our original answer.
45(1 + 2)
