Question

3136 is the least number by which the following must be divided to make them perfect cube​

Answer 1

Answer: 49

Step-by-step explanation:

I didn't understand your question properly, but I will answer it as per my understanding.

3136 = 2 x 1568

3136 = 2 x 2 x 784

3136 = 2 x 2 x 2 x 392

3136 = 2 x 2 x 2 x 2 x 196

3136 = 2 x 2 x 2 x 2 x 2 x 98

3136 = 2 x 2 x 2 x 2 x 2 x 2 x 49

3136 = 2 x 2 x 2 x 2 x 2 x 2 x 7 x 7

$3136 = 2^6 \cdot 7^2$

Therefore, to make it a perfect cube, we have to divide it by $7^2$.
