Question

19. Find the least square
number which is exactly
divisible by each of the
numbers 6, 9, 15 and 20.​

Answer 1

Step-by-step explanation:

Smallest least number divisible by 6,9,15 and 20 is its L.C.M. Its LCM is 180. Therefore there is no factor to form pair of 5, so to make it a perfect square we multiply 180 with 5 to get 900. Hence least square number divisible by6,9,15 and 20 is 900.

Answer 2

Step-by-step explanation:

$\huge{\sf{\underbrace{\overbrace{\pink{AnSwEr}}}}}$
