Question

Find the smallest possible perfect square
number which is exactly divisible by
following set of numbers.
a) 3, 4, 12 and 15​

Answer 1

Answer:

900

Step-by-step explanation:

Numbers which are divisible by 3,4,12 and 15 are the multiples of lcm of these numbers

3=1x3

4=2x2

12=2x2x3

15=3x5

So lcm=2x2x3x5=60

The smallest perfect square which is a multiple of 60 is 60x3x5=900
