Therefore, GCD of numbers 640, 210, 219, 119 is 1

Given Input Data is 640, 210, 219, 119

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

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 219 is 3 x 73

Prime Factorization of 119 is 7 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(640, 210) = 13440

GCD(640, 210) = ( 640 x 210 ) / 13440

GCD(640, 210) = 134400 / 13440

GCD(640, 210) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 219

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

LCM(10, 219) = 2190

GCD(10, 219) = ( 10 x 219 ) / 2190

GCD(10, 219) = 2190 / 2190

GCD(10, 219) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 119

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

LCM(1, 119) = 119

GCD(1, 119) = ( 1 x 119 ) / 119

GCD(1, 119) = 119 / 119

GCD(1, 119) = 1

GCD of 640, 210, 219, 119 is 1
