Therefore, GCD of numbers 12, 555, 291, 764 is 1

Given Input Data is 12, 555, 291, 764

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

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 291 is 3 x 97

Prime Factorization of 764 is 2 x 2 x 191

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(12, 555) = 2220

GCD(12, 555) = ( 12 x 555 ) / 2220

GCD(12, 555) = 6660 / 2220

GCD(12, 555) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 291

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

LCM(3, 291) = 291

GCD(3, 291) = ( 3 x 291 ) / 291

GCD(3, 291) = 873 / 291

GCD(3, 291) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 764

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

LCM(3, 764) = 2292

GCD(3, 764) = ( 3 x 764 ) / 2292

GCD(3, 764) = 2292 / 2292

GCD(3, 764) = 1

GCD of 12, 555, 291, 764 is 1
