What is LCM of 2 and 15?
LCM of 2 and 15 is the least number which is exactly divisible by both 2 and 15
Answer: LCM of 2 and 15 is 30
Explanation:
Least Common Multiple (LCM) of a and b is the smallest number that divides a and b exactly.
The commonly used methods to find the LCM of 2 and 15 are listed below.

LCM of 2 and 15 by Listing Method
List the first few multiples of 2 and 15 and identify the common multiples.
The least among the common multiples is the LCM of 2 and 15
So, by this method, LCM of 2 and 15 is 30

LCM of 2 and 15 by Formula
The formula of LCM is LCM (a, b) = (a × b) / GCF (a, b)
The Greatest Common Factor (GCF) of (2, 15) = 1
Therefore,
LCM of 2 and 15 = (2 × 15) / 1
= 30 / 1
= 30
LCM of 2 and 15 = 30
By both methods, the solution to our question LCM of 2 and 15 is the same.
