Therefore, GCD of numbers 651, 789, 619, 166 is 1

Given Input Data is 651, 789, 619, 166

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

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 789 is 3 x 263

Prime Factorization of 619 is 619

Prime Factorization of 166 is 2 x 83

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(651, 789) = 171213

GCD(651, 789) = ( 651 x 789 ) / 171213

GCD(651, 789) = 513639 / 171213

GCD(651, 789) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 619

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

LCM(3, 619) = 1857

GCD(3, 619) = ( 3 x 619 ) / 1857

GCD(3, 619) = 1857 / 1857

GCD(3, 619) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 166

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

LCM(1, 166) = 166

GCD(1, 166) = ( 1 x 166 ) / 166

GCD(1, 166) = 166 / 166

GCD(1, 166) = 1

GCD of 651, 789, 619, 166 is 1
