## Finding LCM of two numbers 4 and 5 using Prime Factorization Method

Check out the procedure to find the Least Common Multiple of 4 and 5 using the Prime Factorization Method. They are as follows

Step 1: Firstly, find the Prime Factorization of given numbers 4, 5

Prime Factorization of 4 is as such

 2 4 2 2 1

Prime factors of 4 are 2. Prime factorization of 4 in exponent form is:

4 = 22

Prime Factorization of 5 is as follows

 5 5 1

Prime factors of 5 are 5. Prime factorization of 5 in exponent form is:

5 = 51

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 22×51= 20

Therefore, LCM of two numbers 4 and 5 is 20

LCM(4,5) = 20

### Finding LCM of two numbers 4 and 5 using GCF Formula

Go through the simple and easy steps listed to know the Least Common Multiple of 4, 5 using the GCF Formula

Step 1: Find the Greatest Common Factor of 4, 5 initially.

Greatest Common Factor is the largest integer by which both the numbers can be divided. The GCF of 4, 5 is 1.

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(4,5)= 4*5/GCF(4, 5)

= 4*5/1

= 20

Thus, LCM(4,5) using the GCF Formula is 20
