Given Input Data is 642, 618, 887

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

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 887 is 887

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(642, 618) = 66126

GCD(642, 618) = ( 642 x 618 ) / 66126

GCD(642, 618) = 396756 / 66126

GCD(642, 618) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 887

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

LCM(6, 887) = 5322

GCD(6, 887) = ( 6 x 887 ) / 5322

GCD(6, 887) = 5322 / 5322

GCD(6, 887) = 1

GCD of 642, 618, 887 is 1
