Given Input Data is 658, 278, 804, 437

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

Prime Factorization of 658 is 2 x 7 x 47

Prime Factorization of 278 is 2 x 139

Prime Factorization of 804 is 2 x 2 x 3 x 67

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(658, 278) = 91462

GCD(658, 278) = ( 658 x 278 ) / 91462

GCD(658, 278) = 182924 / 91462

GCD(658, 278) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 804

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

LCM(2, 804) = 804

GCD(2, 804) = ( 2 x 804 ) / 804

GCD(2, 804) = 1608 / 804

GCD(2, 804) = 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 658, 278, 804, 437 is 1
