Therefore, GCD of numbers 163, 268, 17, 356 is 1

Given Input Data is 163, 268, 17, 356

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

Prime Factorization of 163 is 163

Prime Factorization of 268 is 2 x 2 x 67

Prime Factorization of 17 is 17

Prime Factorization of 356 is 2 x 2 x 89

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(163, 268) = 43684

GCD(163, 268) = ( 163 x 268 ) / 43684

GCD(163, 268) = 43684 / 43684

GCD(163, 268) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 17

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

LCM(1, 17) = 17

GCD(1, 17) = ( 1 x 17 ) / 17

GCD(1, 17) = 17 / 17

GCD(1, 17) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 356

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

LCM(1, 356) = 356

GCD(1, 356) = ( 1 x 356 ) / 356

GCD(1, 356) = 356 / 356

GCD(1, 356) = 1

GCD of 163, 268, 17, 356 is 1
