Answer 2

Answer:

Hence, 1440 is the smallest number which is divisible by each of 15,20,24,32 and 36.

Step-by-step explanation:

If we have to find the LEAST NUMBER DIVISIBLE BY 15, 20, 24, 32, AND 36, then we have to FIND THEIR LCM. We can do this by prime factorisation.

So, LCM of 15,20,24,32,36 = 2 × 2 × 2 × 2 × 2 × 3 × 3 × 5 = 1440. Hence, 1440 is the smallest number which is divisible by each of 15,20,24,32 and 36.
