Therefore, GCD of numbers 637, 784, 89, 190 is 1

Given Input Data is 637, 784, 89, 190

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

Prime Factorization of 637 is 7 x 7 x 13

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

Prime Factorization of 89 is 89

Prime Factorization of 190 is 2 x 5 x 19

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(637, 784) = 10192

GCD(637, 784) = ( 637 x 784 ) / 10192

GCD(637, 784) = 499408 / 10192

GCD(637, 784) = 49

Step2:

Here we consider the GCD from the above i.e. 49 as first number and the next as 89

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

LCM(49, 89) = 4361

GCD(49, 89) = ( 49 x 89 ) / 4361

GCD(49, 89) = 4361 / 4361

GCD(49, 89) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 190

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

LCM(1, 190) = 190

GCD(1, 190) = ( 1 x 190 ) / 190

GCD(1, 190) = 190 / 190

GCD(1, 190) = 1

GCD of 637, 784, 89, 190 is 1
