Finding GCD of 73, 20, 71 using Prime Factorization

Given Input Data is 73, 20, 71

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

Prime Factorization of 73 is 73

Prime Factorization of 20 is 2 x 2 x 5

Prime Factorization of 71 is 71

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

Finding GCD of 73, 20, 71 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(73, 20) = 1460

GCD(73, 20) = ( 73 x 20 ) / 1460

GCD(73, 20) = 1460 / 1460

GCD(73, 20) = 1


Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 71

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

LCM(1, 71) = 71

GCD(1, 71) = ( 1 x 71 ) / 71

GCD(1, 71) = 71 / 71

GCD(1, 71) = 1

GCD of 73, 20, 71 is 1
