Question

Find the least number which is a perfect square and which is also divisible by 16 18 and 45​

Answer 1

Answer:

3600

Step-by-step explanation:

first we find lcm of 16,18&45

16 = 2*2*2*2

18 = 2*3*3

45 = 3*3*5

therefore the lcm is 2*2*2*2*3*3*5 = 720

here we dont have pair for 5 in the factors list , hence 720 * 5 = 3600 is the least square no. required
