What is the least perfect square which is divisible by 24 30 and 60?

3600 is the least perfect square number which is divisible by 24,30 and 60.

Step-by-step explanation:

Since we have given that

The numbers are 24,30 and 60.

We need to find the least perfect square.

First we find the L.C.M. of 24, 30 and 60 .

So,  L.C.M. of 24, 30 and 60 = 120

But 120 is not a perfect square because:

120=2×2×2×3×5

Since 2,3 and 5 has no pair.

We will multiply with 2,3,and 5.

So, it becomes,

2×2×2×3×5×2×3×5

=3600

Hence, 3600 is the least perfect square number which is divisible by 24,30 and 60.

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
