Given Input Data is 210, 831, 965, 572

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

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 831 is 3 x 277

Prime Factorization of 965 is 5 x 193

Prime Factorization of 572 is 2 x 2 x 11 x 13

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(210, 831) = 58170

GCD(210, 831) = ( 210 x 831 ) / 58170

GCD(210, 831) = 174510 / 58170

GCD(210, 831) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 965

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

LCM(3, 965) = 2895

GCD(3, 965) = ( 3 x 965 ) / 2895

GCD(3, 965) = 2895 / 2895

GCD(3, 965) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 572

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

LCM(1, 572) = 572

GCD(1, 572) = ( 1 x 572 ) / 572

GCD(1, 572) = 572 / 572

GCD(1, 572) = 1

GCD of 210, 831, 965, 572 is 1
