each of the numbers, 8, 12, 15 is
(a) 3600 (5) 9000 (c) 4200 (d) 100​

Answer 1

Answer:  (a) 3600

Step-by-step explanation:

First let's find the LCM of 8,12,15,and 20.

8 = 2 × 2 × 2

12 = 2 × 2 × 3

15 = 3 × 5

20 = 2 × 2 × 5

So the LCM is 2 × 2 × 2 × 3 × 5 = 120

Here is 2,3,5, are not in pairs, we need to in pairs for smallest square number.

=>  120 × 2 × 3 × 5

=>  120 × 30 = 3600.

Hence the number is 2 × 2 × 2 × 2 × 3 × 3 × 5 × 5 = 3600.

=> (a) 3600 is the right answer.
