​

Answer 1

Answer:

LCM of 2800 is 2×2×2×2×5×5×7

So, the smallest number to make a perfect cube is 2800

Answer 2

2800 = 2 × 2 × 2 × 2 × 5 × 5 × 7

If we divide 2800 by 7, then

2800 / 7 = 400

We know 400 is a perfect square as

400 = 20 × 20

So, the smallest number by which 2800 must be divided to get a perfect square is 7
