Therefore, GCD of numbers 888, 428, 161, 428 is 1

Given Input Data is 888, 428, 161, 428

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

Prime Factorization of 888 is 2 x 2 x 2 x 3 x 37

Prime Factorization of 428 is 2 x 2 x 107

Prime Factorization of 161 is 7 x 23

Prime Factorization of 428 is 2 x 2 x 107

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(888, 428) = 95016

GCD(888, 428) = ( 888 x 428 ) / 95016

GCD(888, 428) = 380064 / 95016

GCD(888, 428) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 161

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

LCM(4, 161) = 644

GCD(4, 161) = ( 4 x 161 ) / 644

GCD(4, 161) = 644 / 644

GCD(4, 161) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 428

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

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

GCD(1, 428) = 428 / 428

GCD(1, 428) = 1

GCD of 888, 428, 161, 428 is 1
