Therefore, GCD of numbers 80, 695, 581, 871 is 1

Given Input Data is 80, 695, 581, 871

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

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 695 is 5 x 139

Prime Factorization of 581 is 7 x 83

Prime Factorization of 871 is 13 x 67

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

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(80, 695) = 11120

GCD(80, 695) = ( 80 x 695 ) / 11120

GCD(80, 695) = 55600 / 11120

GCD(80, 695) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 581

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

LCM(5, 581) = 2905

GCD(5, 581) = ( 5 x 581 ) / 2905

GCD(5, 581) = 2905 / 2905

GCD(5, 581) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 871

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

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

GCD(1, 871) = 871 / 871

GCD(1, 871) = 1

GCD of 80, 695, 581, 871 is 1
