Therefore, GCD of numbers 942, 618, 89, 438 is 1

Given Input Data is 942, 618, 89, 438

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

Prime Factorization of 942 is 2 x 3 x 157

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 89 is 89

Prime Factorization of 438 is 2 x 3 x 73

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(942, 618) = 97026

GCD(942, 618) = ( 942 x 618 ) / 97026

GCD(942, 618) = 582156 / 97026

GCD(942, 618) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 89

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

LCM(6, 89) = 534

GCD(6, 89) = ( 6 x 89 ) / 534

GCD(6, 89) = 534 / 534

GCD(6, 89) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 438

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

LCM(1, 438) = 438

GCD(1, 438) = ( 1 x 438 ) / 438

GCD(1, 438) = 438 / 438

GCD(1, 438) = 1

GCD of 942, 618, 89, 438 is 1
