Therefore, GCD of numbers 860, 630, 649, 572 is 1

Given Input Data is 860, 630, 649, 572

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 630 is 2 x 3 x 3 x 5 x 7

Prime Factorization of 649 is 11 x 59

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(860, 630) = 54180

GCD(860, 630) = ( 860 x 630 ) / 54180

GCD(860, 630) = 541800 / 54180

GCD(860, 630) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 649

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

LCM(10, 649) = 6490

GCD(10, 649) = ( 10 x 649 ) / 6490

GCD(10, 649) = 6490 / 6490

GCD(10, 649) = 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 860, 630, 649, 572 is 1
