Final answer:
To find all possible numbers of rows without checking if 8 is a factor, consider the factors of 70 and 150, excluding 8.
Step-by-step explanation:
To find all possible numbers of rows without checking if 8 is a factor, we need to consider the factors of 70 and 150.
Since 70 is divisible by 5 and 14, and 150 is divisible by 5, 10, 15, 30, and 75, we can find the possible numbers of rows by looking at the common factors of 70 and 150, excluding 8.
Therefore, the possible numbers of rows are 5, 10, 14, 15, 30, and 75.
