Find the least common multiple of 12,4, and 9

36

Step-by-step explanation:

12 = 2 * 2 * 3 = 2^2 * 3

4 = 2 * 2 = 2^2

9 = 3 * 3 = 3^2

For the least common multiple, use common and not common factors with the largest exponent.

Use 2^2 and 3^2

LCM = 2^2 * 3^2 = 4 * 9 = 36

3

Step-by-step explanation:

12 divided by 4 is 3, 3 times 3 is 9 bam
