Therefore, GCD of numbers 771, 770, 389 is 1

Given Input Data is 771, 770, 389

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

Prime Factorization of 771 is 3 x 257

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 389 is 389

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(771, 770) = 593670

GCD(771, 770) = ( 771 x 770 ) / 593670

GCD(771, 770) = 593670 / 593670

GCD(771, 770) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 389

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

LCM(1, 389) = 389

GCD(1, 389) = ( 1 x 389 ) / 389

GCD(1, 389) = 389 / 389

GCD(1, 389) = 1

GCD of 771, 770, 389 is 1
