Given Input Data is 870, 237, 478, 219

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

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 237 is 3 x 79

Prime Factorization of 478 is 2 x 239

Prime Factorization of 219 is 3 x 73

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(870, 237) = 68730

GCD(870, 237) = ( 870 x 237 ) / 68730

GCD(870, 237) = 206190 / 68730

GCD(870, 237) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 478

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

LCM(3, 478) = 1434

GCD(3, 478) = ( 3 x 478 ) / 1434

GCD(3, 478) = 1434 / 1434

GCD(3, 478) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 219

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

LCM(1, 219) = 219

GCD(1, 219) = ( 1 x 219 ) / 219

GCD(1, 219) = 219 / 219

GCD(1, 219) = 1

GCD of 870, 237, 478, 219 is 1
