Question

by which least number should be multiplied the following to make perfect square 700​

Answer 1

Answer:

7

Step-by-step explanation:

To find the least number to multiply to 700 to make perfect square,

First we will have to prime factorize 700

700 = 2 * 2 * 5 * 5 * 7

Now, we can see that 2's square is present in the number, 5's square is also in the number and only 7 is single.

So if we multiply 700 with 7, all the factors will be double and thus,

The number will be a perfect square = 4900
