Therefore, GCD of numbers 18, 681, 712, 162 is 1

Given Input Data is 18, 681, 712, 162

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

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 681 is 3 x 227

Prime Factorization of 712 is 2 x 2 x 2 x 89

Prime Factorization of 162 is 2 x 3 x 3 x 3 x 3

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(18, 681) = 4086

GCD(18, 681) = ( 18 x 681 ) / 4086

GCD(18, 681) = 12258 / 4086

GCD(18, 681) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 712

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

LCM(3, 712) = 2136

GCD(3, 712) = ( 3 x 712 ) / 2136

GCD(3, 712) = 2136 / 2136

GCD(3, 712) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 162

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

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

GCD(1, 162) = 162 / 162

GCD(1, 162) = 1

GCD of 18, 681, 712, 162 is 1
