Given Input Data is 820, 202, 770, 437

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

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

Prime Factorization of 202 is 2 x 101

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 437 is 19 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(820, 202) = 82820

GCD(820, 202) = ( 820 x 202 ) / 82820

GCD(820, 202) = 165640 / 82820

GCD(820, 202) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 770

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

LCM(2, 770) = 770

GCD(2, 770) = ( 2 x 770 ) / 770

GCD(2, 770) = 1540 / 770

GCD(2, 770) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 437

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

LCM(2, 437) = 874

GCD(2, 437) = ( 2 x 437 ) / 874

GCD(2, 437) = 874 / 874

GCD(2, 437) = 1

GCD of 820, 202, 770, 437 is 1
