## Finding LCM of two numbers 20 and 25 using Prime Factorization Method

Check out the procedure to find the Least Common Multiple of 20 and 25 using the Prime Factorization Method. They are as follows

Step 1: Firstly, find the Prime Factorization of given numbers 20, 25

Prime Factorization of 20 is as such

 2 20 2 10 5 5 1

Prime factors of 20 are 2,5. Prime factorization of 20 in exponent form is:

20 = 22×51

Prime Factorization of 25 is as follows

 5 25 5 5 1

Prime factors of 25 are 5. Prime factorization of 25 in exponent form is:

25 = 52

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 22×52= 100

Therefore, LCM of two numbers 20 and 25 is 100

LCM(20,25) = 100

### Finding LCM of two numbers 20 and 25 using GCF Formula

Go through the simple and easy steps listed to know the Least Common Multiple of 20, 25 using the GCF Formula

Step 1: Find the Greatest Common Factor of 20, 25 initially.

Greatest Common Factor is the largest integer by which both the numbers can be divided. The GCF of 20, 25 is 5.

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(20,25)= 20*25/GCF(20, 25)

= 20*25/5

= 100

Thus, LCM(20,25) using the GCF Formula is 100
