Therefore, GCD of numbers 621, 437, 50, 784 is 1

Given Input Data is 621, 437, 50, 784

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

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

Prime Factorization of 437 is 19 x 23

Prime Factorization of 50 is 2 x 5 x 5

Prime Factorization of 784 is 2 x 2 x 2 x 2 x 7 x 7

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(621, 437) = 11799

GCD(621, 437) = ( 621 x 437 ) / 11799

GCD(621, 437) = 271377 / 11799

GCD(621, 437) = 23

Step2:

Here we consider the GCD from the above i.e. 23 as first number and the next as 50

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

LCM(23, 50) = 1150

GCD(23, 50) = ( 23 x 50 ) / 1150

GCD(23, 50) = 1150 / 1150

GCD(23, 50) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 784

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

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

GCD(1, 784) = 784 / 784

GCD(1, 784) = 1

GCD of 621, 437, 50, 784 is 1
