Given Input Data is 78, 892, 450, 439

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

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 892 is 2 x 2 x 223

Prime Factorization of 450 is 2 x 3 x 3 x 5 x 5

Prime Factorization of 439 is 439

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(78, 892) = 34788

GCD(78, 892) = ( 78 x 892 ) / 34788

GCD(78, 892) = 69576 / 34788

GCD(78, 892) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 450

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

LCM(2, 450) = 450

GCD(2, 450) = ( 2 x 450 ) / 450

GCD(2, 450) = 900 / 450

GCD(2, 450) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 439

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

LCM(2, 439) = 878

GCD(2, 439) = ( 2 x 439 ) / 878

GCD(2, 439) = 878 / 878

GCD(2, 439) = 1

GCD of 78, 892, 450, 439 is 1
