Given Input Data is 955, 985, 28, 163

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

Prime Factorization of 955 is 5 x 191

Prime Factorization of 985 is 5 x 197

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 163 is 163

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(955, 985) = 188135

GCD(955, 985) = ( 955 x 985 ) / 188135

GCD(955, 985) = 940675 / 188135

GCD(955, 985) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 28

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

LCM(5, 28) = 140

GCD(5, 28) = ( 5 x 28 ) / 140

GCD(5, 28) = 140 / 140

GCD(5, 28) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 163

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

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

GCD(1, 163) = 163 / 163

GCD(1, 163) = 1

GCD of 955, 985, 28, 163 is 1
