Copy and complete the table of multiples below. (Count by 2’s and count by 3’s). Homework Help ✎
Write down all the numbers that appear in both rows. Describe any pattern(s) that you notice.
6, 12, and 18 are in both rows.
What do you notice about these numbers? Are they multiples of a number other than 2 and 3?
What is the smallest number that appears in both rows? This number is said to be the least common multiple of 2 and 3.
Looking at part (a) of this problem may make this easier.
Find three more common multiples of 2 and 3.
Keep counting by 2's and 3's.
Three more common multiples of 2 and 3 are 24, 30, and 36.
Can you find the largest number that is a common multiple of both 2 and 3? If so, what is it? If not, explain why not.
The largest common multiple would be the greatest number that is a multiple of both of the two factors. Refer to part (a) again.
