now, Lets take LCM of 15,18,25

LCM= 450

So, the smallest perfect square of 15,18,25 is 450

Step-by-step explanation:

Answer 2

factors of 15 are 3×5

factors of 18 are 2×3×3

factors of 25 are 5×5

arranging them in manner of square,

=3×3×3×5×5×5×2

here 3 and 5 are common so numbers which are left =3×5×2

so we have to multiply them with 3×5×2 in order to get a perfect square

so 3×3×5×5×2×2

now we get 3×5×2=30

smallest square no =30×30=900
