LCM of 14 and 21 is 42.
Step-by-step explanation:
According to the question
We have to find the LCM of 14 and 21 by prime factorization method.
We know that, LCM stands for lowest common factor of any given numbers.
Given two numbers are 14 and 21.
14 = 2 x 7
21 = 3 x 7
∴ LCM of 14 and 21 = 2 x 3 x 7
= 42
Hence the LCM of 14 and 21 will be 42.
