Therefore, GCD of numbers 863, 662, 76, 770 is 1

Given Input Data is 863, 662, 76, 770

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

Prime Factorization of 863 is 863

Prime Factorization of 662 is 2 x 331

Prime Factorization of 76 is 2 x 2 x 19

Prime Factorization of 770 is 2 x 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(863, 662) = 571306

GCD(863, 662) = ( 863 x 662 ) / 571306

GCD(863, 662) = 571306 / 571306

GCD(863, 662) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 76

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

LCM(1, 76) = 76

GCD(1, 76) = ( 1 x 76 ) / 76

GCD(1, 76) = 76 / 76

GCD(1, 76) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 770

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

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

GCD(1, 770) = 770 / 770

GCD(1, 770) = 1

GCD of 863, 662, 76, 770 is 1
