Finding LCM of two numbers 12 and 18 using Prime Factorization Method

Check out the procedure to find the Least Common Multiple of 12 and 18 using the Prime Factorization Method. They are as follows

Step 1: Firstly, find the Prime Factorization of given numbers 12, 18

Prime Factorization of 12 is as such


2 12
2 6
3 3
1

Prime factors of 12 are 2,3. Prime factorization of 12 in exponent form is:

12 = 22×31

Prime Factorization of 18 is as follows


2 18
3 9
3 3
1

Prime factors of 18 are 2,3. Prime factorization of 18 in exponent form is:

18 = 21×32

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 22×32= 36

Therefore, LCM of two numbers 12 and 18 is 36

LCM(12,18) = 36

Finding LCM of two numbers 12 and 18 using GCF Formula

Go through the simple and easy steps listed to know the Least Common Multiple of 12, 18 using the GCF Formula

Step 1: Find the Greatest Common Factor of 12, 18 initially.

Greatest Common Factor is the largest integer by which both the numbers can be divided. The GCF of 12, 18 is 6.

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(12,18)= 12*18/GCF(12, 18)

= 12*18/6

= 36

Thus, LCM(12,18) using the GCF Formula is 36
