Therefore, GCD of numbers 636, 213, 94, 155 is 1

Given Input Data is 636, 213, 94, 155

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

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 213 is 3 x 71

Prime Factorization of 94 is 2 x 47

Prime Factorization of 155 is 5 x 31

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(636, 213) = 45156

GCD(636, 213) = ( 636 x 213 ) / 45156

GCD(636, 213) = 135468 / 45156

GCD(636, 213) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 94

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

LCM(3, 94) = 282

GCD(3, 94) = ( 3 x 94 ) / 282

GCD(3, 94) = 282 / 282

GCD(3, 94) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 155

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

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

GCD(1, 155) = 155 / 155

GCD(1, 155) = 1

GCD of 636, 213, 94, 155 is 1
