Given Input Data is 939, 978, 654, 437

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

Prime Factorization of 939 is 3 x 313

Prime Factorization of 978 is 2 x 3 x 163

Prime Factorization of 654 is 2 x 3 x 109

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(939, 978) = 306114

GCD(939, 978) = ( 939 x 978 ) / 306114

GCD(939, 978) = 918342 / 306114

GCD(939, 978) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 654

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

LCM(3, 654) = 654

GCD(3, 654) = ( 3 x 654 ) / 654

GCD(3, 654) = 1962 / 654

GCD(3, 654) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 437

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

LCM(3, 437) = 1311

GCD(3, 437) = ( 3 x 437 ) / 1311

GCD(3, 437) = 1311 / 1311

GCD(3, 437) = 1

GCD of 939, 978, 654, 437 is 1
