Therefore, GCD of numbers 938, 978, 57, 911 is 1

Given Input Data is 938, 978, 57, 911

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

Prime Factorization of 938 is 2 x 7 x 67

Prime Factorization of 978 is 2 x 3 x 163

Prime Factorization of 57 is 3 x 19

Prime Factorization of 911 is 911

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(938, 978) = 458682

GCD(938, 978) = ( 938 x 978 ) / 458682

GCD(938, 978) = 917364 / 458682

GCD(938, 978) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 57

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

LCM(2, 57) = 114

GCD(2, 57) = ( 2 x 57 ) / 114

GCD(2, 57) = 114 / 114

GCD(2, 57) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 911

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

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

GCD(1, 911) = 911 / 911

GCD(1, 911) = 1

GCD of 938, 978, 57, 911 is 1
