Write 18 multiples of 9 and 6 also wrote common multiples .

Answer»

Answer:

One WAY of solving this problem is to write out MULTIPLES of each and SEE what is common to the list:

6, 12, 18, 24, 30, 36, ... multiples of 6

9, 18, 27, 36, 45, ... multiples of 9

We see that the numbers 18 and 36 are both common multiples of 6 and 9. The LEAST common multiple is the smallest which is 18.
