Given Input Data is 441, 215, 390, 934

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

Prime Factorization of 441 is 3 x 3 x 7 x 7

Prime Factorization of 215 is 5 x 43

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 934 is 2 x 467

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(441, 215) = 94815

GCD(441, 215) = ( 441 x 215 ) / 94815

GCD(441, 215) = 94815 / 94815

GCD(441, 215) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 390

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

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

GCD(1, 390) = 390 / 390

GCD(1, 390) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 934

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

LCM(1, 934) = 934

GCD(1, 934) = ( 1 x 934 ) / 934

GCD(1, 934) = 934 / 934

GCD(1, 934) = 1

GCD of 441, 215, 390, 934 is 1
