Given Input Data is 428, 976, 161

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

Prime Factorization of 428 is 2 x 2 x 107

Prime Factorization of 976 is 2 x 2 x 2 x 2 x 61

Prime Factorization of 161 is 7 x 23

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(428, 976) = 104432

GCD(428, 976) = ( 428 x 976 ) / 104432

GCD(428, 976) = 417728 / 104432

GCD(428, 976) = 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

GCD of 428, 976, 161 is 1
