Finding GCD of 71, 20, 11 using Prime Factorization

Given Input Data is 71, 20, 11

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 71 is 71

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 11 is 11

The above numbers do not have any common prime factor. So GCD is 1

Finding GCD of 71, 20, 11 using LCM Formula

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(71, 20) = 1420

GCD(71, 20) = ( 71 x 20 ) / 1420

GCD(71, 20) = 1420 / 1420

GCD(71, 20) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 11

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 11) = 11

GCD(1, 11) = ( 1 x 11 ) / 11

GCD(1, 11) = 11 / 11

GCD(1, 11) = 1

GCD of 71, 20, 11 is 1
