Therefore, GCD of numbers 386, 155, 568, 779 is 1

Given Input Data is 386, 155, 568, 779

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

Prime Factorization of 386 is 2 x 193

Prime Factorization of 155 is 5 x 31

Prime Factorization of 568 is 2 x 2 x 2 x 71

Prime Factorization of 779 is 19 x 41

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(386, 155) = 59830

GCD(386, 155) = ( 386 x 155 ) / 59830

GCD(386, 155) = 59830 / 59830

GCD(386, 155) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 568

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

LCM(1, 568) = 568

GCD(1, 568) = ( 1 x 568 ) / 568

GCD(1, 568) = 568 / 568

GCD(1, 568) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 779

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

LCM(1, 779) = 779

GCD(1, 779) = ( 1 x 779 ) / 779

GCD(1, 779) = 779 / 779

GCD(1, 779) = 1

GCD of 386, 155, 568, 779 is 1
