Therefore, GCD of numbers 863, 388, 42, 851 is 1

Given Input Data is 863, 388, 42, 851

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

Prime Factorization of 863 is 863

Prime Factorization of 388 is 2 x 2 x 97

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 851 is 23 x 37

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(863, 388) = 334844

GCD(863, 388) = ( 863 x 388 ) / 334844

GCD(863, 388) = 334844 / 334844

GCD(863, 388) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 42

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

LCM(1, 42) = 42

GCD(1, 42) = ( 1 x 42 ) / 42

GCD(1, 42) = 42 / 42

GCD(1, 42) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 851

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

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

GCD(1, 851) = 851 / 851

GCD(1, 851) = 1

GCD of 863, 388, 42, 851 is 1
