Therefore, GCD of numbers 290, 860, 437, 211 is 1

Given Input Data is 290, 860, 437, 211

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

Prime Factorization of 290 is 2 x 5 x 29

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 437 is 19 x 23

Prime Factorization of 211 is 211

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(290, 860) = 24940

GCD(290, 860) = ( 290 x 860 ) / 24940

GCD(290, 860) = 249400 / 24940

GCD(290, 860) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 437

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

LCM(10, 437) = 4370

GCD(10, 437) = ( 10 x 437 ) / 4370

GCD(10, 437) = 4370 / 4370

GCD(10, 437) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 211

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

LCM(1, 211) = 211

GCD(1, 211) = ( 1 x 211 ) / 211

GCD(1, 211) = 211 / 211

GCD(1, 211) = 1

GCD of 290, 860, 437, 211 is 1
