Step-by-step
WE KNOW
Product: 48
First factor: 8
FIND
second factor
Step 1 · Find second factor
8 × ? = 48
First factor × second factor = product
Divide the product by the first factor.
Second factor = 48 ÷ 8
Think: 8 × ? = 48
5 × 8 = 40
One more group: 40 + 8 = 48
6 groups of 8 make 48
Second factor = 6
Check
Put the numbers back in. Both sides should match.
