Given Input Data is 860, 570, 429, 905

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

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

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 429 is 3 x 11 x 13

Prime Factorization of 905 is 5 x 181

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(860, 570) = 49020

GCD(860, 570) = ( 860 x 570 ) / 49020

GCD(860, 570) = 490200 / 49020

GCD(860, 570) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 429

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

LCM(10, 429) = 4290

GCD(10, 429) = ( 10 x 429 ) / 4290

GCD(10, 429) = 4290 / 4290

GCD(10, 429) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 905

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

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

GCD(1, 905) = 905 / 905

GCD(1, 905) = 1

GCD of 860, 570, 429, 905 is 1
