Finding LCM of two numbers 14 and 21 using Prime Factorization Method

Check out the procedure to find the Least Common Multiple of 14 and 21 using the Prime Factorization Method. They are as follows

Step 1: Firstly, find the Prime Factorization of given numbers 14, 21

Prime Factorization of 14 is as such


2 14
7 7
1

Prime factors of 14 are 2,7. Prime factorization of 14 in exponent form is:

14 = 21×71

Prime Factorization of 21 is as follows


3 21
7 7
1

Prime factors of 21 are 3,7. Prime factorization of 21 in exponent form is:

21 = 31×71

Step 2: Multiply together each of the Prime Numbers with the highest power to obtain the Least Common Multiple

On doing so, you will get the resultant equation as 21×31×71= 42

Therefore, LCM of two numbers 14 and 21 is 42

LCM(14,21) = 42

Finding LCM of two numbers 14 and 21 using GCF Formula

Go through the simple and easy steps listed to know the Least Common Multiple of 14, 21 using the GCF Formula

Step 1: Find the Greatest Common Factor of 14, 21 initially.

Greatest Common Factor is the largest integer by which both the numbers can be divided. The GCF of 14, 21 is 7.

Simply use the GCF obtained in the formula to find the Least Common Multiple i.e. LCM(a,b) =a*b/GCF(a,b)

Substitute the inputs in the formula and you will get as under

LCM(14,21)= 14*21/GCF(14, 21)

= 14*21/7

= 42

Thus, LCM(14,21) using the GCF Formula is 42
