Therefore, GCD of numbers 385, 430, 80, 706 is 1

Given Input Data is 385, 430, 80, 706

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

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 430 is 2 x 5 x 43

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 706 is 2 x 353

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(385, 430) = 33110

GCD(385, 430) = ( 385 x 430 ) / 33110

GCD(385, 430) = 165550 / 33110

GCD(385, 430) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 80

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

LCM(5, 80) = 80

GCD(5, 80) = ( 5 x 80 ) / 80

GCD(5, 80) = 400 / 80

GCD(5, 80) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 706

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

LCM(5, 706) = 3530

GCD(5, 706) = ( 5 x 706 ) / 3530

GCD(5, 706) = 3530 / 3530

GCD(5, 706) = 1

GCD of 385, 430, 80, 706 is 1
