Question

find the least number of soldiers in a regiment such that they stand in rows of 15 20 25

Answer 1

Answer:

900 is the least perfect square number of soldiers.

Step-by-step explanation:

Since we have given that

15,20 and 25

So, LCM of 15, 20, 25 = 60 = 2×2×3×5

since we can see that 3 and 5 does not have pairs to get the square

So, we multiply by 3 and 5 on both the sides ,

\begin{gathered}2^2\times 3\times 5\times 3\times 5\times =60\times 15\\\\=900\\\\=\sqrt{900}=30\end{gathered}

×3×5×3×5×=60×15

=900

=

900

=30

Hence, 900 is the least perfect square number of soldiers.
