Therefore, GCD of numbers 916, 668, 789, 477 is 1

Given Input Data is 916, 668, 789, 477

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

Prime Factorization of 916 is 2 x 2 x 229

Prime Factorization of 668 is 2 x 2 x 167

Prime Factorization of 789 is 3 x 263

Prime Factorization of 477 is 3 x 3 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(916, 668) = 152972

GCD(916, 668) = ( 916 x 668 ) / 152972

GCD(916, 668) = 611888 / 152972

GCD(916, 668) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 789

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

LCM(4, 789) = 3156

GCD(4, 789) = ( 4 x 789 ) / 3156

GCD(4, 789) = 3156 / 3156

GCD(4, 789) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 477

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

LCM(1, 477) = 477

GCD(1, 477) = ( 1 x 477 ) / 477

GCD(1, 477) = 477 / 477

GCD(1, 477) = 1

GCD of 916, 668, 789, 477 is 1
