Given Input Data is 972, 544, 385, 805

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

Prime Factorization of 972 is 2 x 2 x 3 x 3 x 3 x 3 x 3

Prime Factorization of 544 is 2 x 2 x 2 x 2 x 2 x 17

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 805 is 5 x 7 x 23

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(972, 544) = 132192

GCD(972, 544) = ( 972 x 544 ) / 132192

GCD(972, 544) = 528768 / 132192

GCD(972, 544) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 385

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

LCM(4, 385) = 1540

GCD(4, 385) = ( 4 x 385 ) / 1540

GCD(4, 385) = 1540 / 1540

GCD(4, 385) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 805

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

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

GCD(1, 805) = 805 / 805

GCD(1, 805) = 1

GCD of 972, 544, 385, 805 is 1
