Answer: You need to find the multiples of each of the numbers and choose the largest one that each number has
Step-by-step explanation:
42 write what can be multiplied to get 42
1 and 42 , 2 and 21, 3 and 14, 6 and 7
70 write what can be multiplied to get 70
1 and 70, 2 and 35, 5 and 14, 7 and 10
56- write what can be multiplied to get 56
1 and 56, 2 and 28, 4 and 14, 7 and 8
Now look back and see what numbers they all have in common, which is 2 and 14 in this case
You pick the bigger number because it is a GCF problem, which is 14, and that is the number of rows
