So the Greatest Common Divisior 94, 42, 63, 71 is 1.

Therefore, GCD of numbers 94, 42, 63, 71 is 1

Given Input Data is 94, 42, 63, 71

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

Prime Factorization of 94 is 2 x 47

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 71 is 71

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(94, 42) = 1974

GCD(94, 42) = ( 94 x 42 ) / 1974

GCD(94, 42) = 3948 / 1974

GCD(94, 42) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 63

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

LCM(2, 63) = 126

GCD(2, 63) = ( 2 x 63 ) / 126

GCD(2, 63) = 126 / 126

GCD(2, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 71

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

LCM(1, 71) = 71

GCD(1, 71) = ( 1 x 71 ) / 71

GCD(1, 71) = 71 / 71

GCD(1, 71) = 1

GCD of 94, 42, 63, 71 is 1
