Given Input Data is 780, 545, 797, 801

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

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 545 is 5 x 109

Prime Factorization of 797 is 797

Prime Factorization of 801 is 3 x 3 x 89

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(780, 545) = 85020

GCD(780, 545) = ( 780 x 545 ) / 85020

GCD(780, 545) = 425100 / 85020

GCD(780, 545) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 797

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

LCM(5, 797) = 3985

GCD(5, 797) = ( 5 x 797 ) / 3985

GCD(5, 797) = 3985 / 3985

GCD(5, 797) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 801

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

LCM(1, 801) = 801

GCD(1, 801) = ( 1 x 801 ) / 801

GCD(1, 801) = 801 / 801

GCD(1, 801) = 1

GCD of 780, 545, 797, 801 is 1
