Given Input Data is 870, 964, 439, 297

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 964 is 2 x 2 x 241

Prime Factorization of 439 is 439

Prime Factorization of 297 is 3 x 3 x 3 x 11

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, 964) = 419340

GCD(870, 964) = ( 870 x 964 ) / 419340

GCD(870, 964) = 838680 / 419340

GCD(870, 964) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 439

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

LCM(2, 439) = 878

GCD(2, 439) = ( 2 x 439 ) / 878

GCD(2, 439) = 878 / 878

GCD(2, 439) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 297

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

LCM(1, 297) = 297

GCD(1, 297) = ( 1 x 297 ) / 297

GCD(1, 297) = 297 / 297

GCD(1, 297) = 1

GCD of 870, 964, 439, 297 is 1
