=2×2×5×5×2×2×28
=(2×2)×(5×5)×(2×2)×(2×2)×7
least number is 7

Answer 2

(6)

Prime factorization of 11200 = 2 * 2 * 2 * 2 * 2 * 2 * 5 * 5 * 7.

As you can see 2 and 5 are paired in group and 7 is left unpaired.

We have to divide 11200 by 7.

= > 11200 ÷ 7

= > 1600

= > 2 * 2 * 2 * 2 * 2 * 2 * 5 * 5.

Which is a perfect square.

Therefore, the lest number is 7.
