Therefore, GCD of numbers 475, 779, 80, 440 is 1

Given Input Data is 475, 779, 80, 440

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

Prime Factorization of 475 is 5 x 5 x 19

Prime Factorization of 779 is 19 x 41

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

Prime Factorization of 440 is 2 x 2 x 2 x 5 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(475, 779) = 19475

GCD(475, 779) = ( 475 x 779 ) / 19475

GCD(475, 779) = 370025 / 19475

GCD(475, 779) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 80

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

LCM(19, 80) = 1520

GCD(19, 80) = ( 19 x 80 ) / 1520

GCD(19, 80) = 1520 / 1520

GCD(19, 80) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 440

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

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

GCD(1, 440) = 440 / 440

GCD(1, 440) = 1

GCD of 475, 779, 80, 440 is 1
