Therefore, GCD of numbers 773, 438, 127, 689 is 1

Given Input Data is 773, 438, 127, 689

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

Prime Factorization of 773 is 773

Prime Factorization of 438 is 2 x 3 x 73

Prime Factorization of 127 is 127

Prime Factorization of 689 is 13 x 53

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(773, 438) = 338574

GCD(773, 438) = ( 773 x 438 ) / 338574

GCD(773, 438) = 338574 / 338574

GCD(773, 438) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 127

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

LCM(1, 127) = 127

GCD(1, 127) = ( 1 x 127 ) / 127

GCD(1, 127) = 127 / 127

GCD(1, 127) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 689

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

LCM(1, 689) = 689

GCD(1, 689) = ( 1 x 689 ) / 689

GCD(1, 689) = 689 / 689

GCD(1, 689) = 1

GCD of 773, 438, 127, 689 is 1
