Therefore, GCD of numbers 620, 290, 11, 471 is 1

Given Input Data is 620, 290, 11, 471

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

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 290 is 2 x 5 x 29

Prime Factorization of 11 is 11

Prime Factorization of 471 is 3 x 157

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(620, 290) = 17980

GCD(620, 290) = ( 620 x 290 ) / 17980

GCD(620, 290) = 179800 / 17980

GCD(620, 290) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 11

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

LCM(10, 11) = 110

GCD(10, 11) = ( 10 x 11 ) / 110

GCD(10, 11) = 110 / 110

GCD(10, 11) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 471

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

LCM(1, 471) = 471

GCD(1, 471) = ( 1 x 471 ) / 471

GCD(1, 471) = 471 / 471

GCD(1, 471) = 1

GCD of 620, 290, 11, 471 is 1
