Question

Find two natural numbers that are multiples of both 12 and 15​

Answer 1

Answer:

60 and 120

Step-by-step explanation:

The LCM of 12 and 15 is 60

The smallest natural number that would be a multiple of 12 and 15 would be 60.

To find the second number, all you do is multiply 60 by 2 and you get 120.

(60 * 2 = 120)

Answer 2

Answer:

  180 and 420

Step-by-step explanation:

The greatest common factor of 12 and 15 is 3, so the least common multiple will be (12)(15)/3 = 60.

Any natural number multiple of 60 will be an answer to your question. For multiples 3 and 7, your two numbers are 180 and 420.

  180 = 12 × 15

  420 = 12 × 35 = 15 × 28
