So the Greatest Common Divisior 791, 534, 155, 385 is 1.

Therefore, GCD of numbers 791, 534, 155, 385 is 1

Given Input Data is 791, 534, 155, 385

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

Prime Factorization of 791 is 7 x 113

Prime Factorization of 534 is 2 x 3 x 89

Prime Factorization of 155 is 5 x 31

Prime Factorization of 385 is 5 x 7 x 11

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(791, 534) = 422394

GCD(791, 534) = ( 791 x 534 ) / 422394

GCD(791, 534) = 422394 / 422394

GCD(791, 534) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 155

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

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

GCD(1, 155) = 155 / 155

GCD(1, 155) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 385

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

LCM(1, 385) = 385

GCD(1, 385) = ( 1 x 385 ) / 385

GCD(1, 385) = 385 / 385

GCD(1, 385) = 1

GCD of 791, 534, 155, 385 is 1
