Therefore, GCD of numbers 907, 419, 21, 187 is 1

Given Input Data is 907, 419, 21, 187

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

Prime Factorization of 907 is 907

Prime Factorization of 419 is 419

Prime Factorization of 21 is 3 x 7

Prime Factorization of 187 is 11 x 17

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(907, 419) = 380033

GCD(907, 419) = ( 907 x 419 ) / 380033

GCD(907, 419) = 380033 / 380033

GCD(907, 419) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 21

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

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

GCD(1, 21) = 21 / 21

GCD(1, 21) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 187

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

LCM(1, 187) = 187

GCD(1, 187) = ( 1 x 187 ) / 187

GCD(1, 187) = 187 / 187

GCD(1, 187) = 1

GCD of 907, 419, 21, 187 is 1
