Therefore, GCD of numbers 256, 394, 93, 820 is 1

Given Input Data is 256, 394, 93, 820

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

Prime Factorization of 256 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 394 is 2 x 197

Prime Factorization of 93 is 3 x 31

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

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(256, 394) = 50432

GCD(256, 394) = ( 256 x 394 ) / 50432

GCD(256, 394) = 100864 / 50432

GCD(256, 394) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 93

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

LCM(2, 93) = 186

GCD(2, 93) = ( 2 x 93 ) / 186

GCD(2, 93) = 186 / 186

GCD(2, 93) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 820

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

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

GCD(1, 820) = 820 / 820

GCD(1, 820) = 1

GCD of 256, 394, 93, 820 is 1
