Therefore, GCD of numbers 758, 938, 911, 780 is 1

Given Input Data is 758, 938, 911, 780

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

Prime Factorization of 758 is 2 x 379

Prime Factorization of 938 is 2 x 7 x 67

Prime Factorization of 911 is 911

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

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(758, 938) = 355502

GCD(758, 938) = ( 758 x 938 ) / 355502

GCD(758, 938) = 711004 / 355502

GCD(758, 938) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 911

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

LCM(2, 911) = 1822

GCD(2, 911) = ( 2 x 911 ) / 1822

GCD(2, 911) = 1822 / 1822

GCD(2, 911) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 780

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

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

GCD(1, 780) = 780 / 780

GCD(1, 780) = 1

GCD of 758, 938, 911, 780 is 1
