Given Input Data is 909, 792, 820, 619

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

Prime Factorization of 909 is 3 x 3 x 101

Prime Factorization of 792 is 2 x 2 x 2 x 3 x 3 x 11

Prime Factorization of 820 is 2 x 2 x 5 x 41

Prime Factorization of 619 is 619

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(909, 792) = 79992

GCD(909, 792) = ( 909 x 792 ) / 79992

GCD(909, 792) = 719928 / 79992

GCD(909, 792) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 820

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

LCM(9, 820) = 7380

GCD(9, 820) = ( 9 x 820 ) / 7380

GCD(9, 820) = 7380 / 7380

GCD(9, 820) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 619

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

LCM(1, 619) = 619

GCD(1, 619) = ( 1 x 619 ) / 619

GCD(1, 619) = 619 / 619

GCD(1, 619) = 1

GCD of 909, 792, 820, 619 is 1
