Question

Which is the least perfect cube that is divisible by 2, 3, 4 & 6?

Answer 1

Answer:

Step-by-step explanation:

LCM(3, 4, 5, 6)= 360

Now find the four digit no. multiple of 360 which is > 2497

For that we first divide 2497 with 360 to get the least no. greater than 2497 which is divisible by 3, 4, 5, 6.

So, 2497/360

= 6.9361

= 7 approx.

Therefore the 4 digit no. multiple of 360 (>2497) would be 360 x 7 = 2520

Let the required no. be X

so the equation would be:

X + 2497 =2520

Or, X = 2520 - 2497

Or, X = 23.

Hence, the least no. which should be added to 2497 and divisible by 3, 4, 5 and 6 is 23.
