Therefore, GCD of numbers 834, 430, 64, 621 is 1

Given Input Data is 834, 430, 64, 621

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

Prime Factorization of 834 is 2 x 3 x 139

Prime Factorization of 430 is 2 x 5 x 43

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 621 is 3 x 3 x 3 x 23

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(834, 430) = 179310

GCD(834, 430) = ( 834 x 430 ) / 179310

GCD(834, 430) = 358620 / 179310

GCD(834, 430) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 64

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

LCM(2, 64) = 64

GCD(2, 64) = ( 2 x 64 ) / 64

GCD(2, 64) = 128 / 64

GCD(2, 64) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 621

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

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

GCD(2, 621) = 1242 / 1242

GCD(2, 621) = 1

GCD of 834, 430, 64, 621 is 1
