Therefore, GCD of numbers 751, 820, 28, 321 is 1

Given Input Data is 751, 820, 28, 321

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

Prime Factorization of 751 is 751

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

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 321 is 3 x 107

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(751, 820) = 615820

GCD(751, 820) = ( 751 x 820 ) / 615820

GCD(751, 820) = 615820 / 615820

GCD(751, 820) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 28

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

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

GCD(1, 28) = 28 / 28

GCD(1, 28) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 321

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

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

GCD(1, 321) = 321 / 321

GCD(1, 321) = 1

GCD of 751, 820, 28, 321 is 1
