Therefore, GCD of numbers 77, 287, 626, 188 is 1

Given Input Data is 77, 287, 626, 188

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

Prime Factorization of 77 is 7 x 11

Prime Factorization of 287 is 7 x 41

Prime Factorization of 626 is 2 x 313

Prime Factorization of 188 is 2 x 2 x 47

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(77, 287) = 3157

GCD(77, 287) = ( 77 x 287 ) / 3157

GCD(77, 287) = 22099 / 3157

GCD(77, 287) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 626

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

LCM(7, 626) = 4382

GCD(7, 626) = ( 7 x 626 ) / 4382

GCD(7, 626) = 4382 / 4382

GCD(7, 626) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 188

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

LCM(1, 188) = 188

GCD(1, 188) = ( 1 x 188 ) / 188

GCD(1, 188) = 188 / 188

GCD(1, 188) = 1

GCD of 77, 287, 626, 188 is 1
