How did the multiplication combinationsyou wrote for 12 18 21 help you find some cominations for 120 180 210?
To answer this question you need to start with the "... combinations you wrote for 12, 18 and 21". Notice that the numbers in the second set are each 10 times the numbers in the first set. Combinations for numbers in the second set can be found by adding "*10" or "*5*2" to the combinations for the first set. You could also say: 12 = 2*2*3; 120 = 2*2*3*5*2 = 4*15*2, and many other variations on this theme.
