Answer:

The 15 multiples of 12 are 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168 and 180.

Step-by-step explanation:

Multiples of 12 can be found out by multiplying 12 with various natural numbers.

Here, we need to find the first 15 multiples, so we will multiply 12 by the first 15 natural numbers.

We get that:

12 × 1 =12

12 ×2 = 24

12 × 3 =36

12 × 4 = 48

12 × 5 = 60

12 × 6 = 72

12 × 7 = 84

12 × 8 = 96

12 × 9 = 108

12 × 10 = 120

12 × 11 = 132

12 × 12 = 144

12 × 13 = 156

12 × 14 = 168

12 × 15 = 180

Therefore, the 15 multiples of 12 are 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168 and 180.
