Therefore, GCD of numbers 215, 450, 163, 156 is 1

Given Input Data is 215, 450, 163, 156

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

Prime Factorization of 215 is 5 x 43

Prime Factorization of 450 is 2 x 3 x 3 x 5 x 5

Prime Factorization of 163 is 163

Prime Factorization of 156 is 2 x 2 x 3 x 13

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(215, 450) = 19350

GCD(215, 450) = ( 215 x 450 ) / 19350

GCD(215, 450) = 96750 / 19350

GCD(215, 450) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 163

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

LCM(5, 163) = 815

GCD(5, 163) = ( 5 x 163 ) / 815

GCD(5, 163) = 815 / 815

GCD(5, 163) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 156

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

LCM(1, 156) = 156

GCD(1, 156) = ( 1 x 156 ) / 156

GCD(1, 156) = 156 / 156

GCD(1, 156) = 1

GCD of 215, 450, 163, 156 is 1
