Therefore, GCD of numbers 75, 378, 530, 439 is 1

Given Input Data is 75, 378, 530, 439

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

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 378 is 2 x 3 x 3 x 3 x 7

Prime Factorization of 530 is 2 x 5 x 53

Prime Factorization of 439 is 439

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(75, 378) = 9450

GCD(75, 378) = ( 75 x 378 ) / 9450

GCD(75, 378) = 28350 / 9450

GCD(75, 378) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 530

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

LCM(3, 530) = 1590

GCD(3, 530) = ( 3 x 530 ) / 1590

GCD(3, 530) = 1590 / 1590

GCD(3, 530) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 439

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

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

GCD(1, 439) = 439 / 439

GCD(1, 439) = 1

GCD of 75, 378, 530, 439 is 1
