Given Input Data is 618, 933, 670, 686

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

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 933 is 3 x 311

Prime Factorization of 670 is 2 x 5 x 67

Prime Factorization of 686 is 2 x 7 x 7 x 7

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(618, 933) = 192198

GCD(618, 933) = ( 618 x 933 ) / 192198

GCD(618, 933) = 576594 / 192198

GCD(618, 933) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 670

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

LCM(3, 670) = 2010

GCD(3, 670) = ( 3 x 670 ) / 2010

GCD(3, 670) = 2010 / 2010

GCD(3, 670) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 686

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

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

GCD(1, 686) = 686 / 686

GCD(1, 686) = 1

GCD of 618, 933, 670, 686 is 1
