Question

14 and 21,Find the LCM of the given number by prime factorisation method.

Answer 1

Heya !!





Prime factorisation of 14 = 2 × 7



Prime factorisation of 21 = 3 × 7




LCM of 14 and 21 = 7 × 2 × 3 = 42.

Answer 2

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.
