Therefore, GCD of numbers 781, 660, 884, 585 is 1

Given Input Data is 781, 660, 884, 585

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

Prime Factorization of 781 is 11 x 71

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 884 is 2 x 2 x 13 x 17

Prime Factorization of 585 is 3 x 3 x 5 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(781, 660) = 46860

GCD(781, 660) = ( 781 x 660 ) / 46860

GCD(781, 660) = 515460 / 46860

GCD(781, 660) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 884

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

LCM(11, 884) = 9724

GCD(11, 884) = ( 11 x 884 ) / 9724

GCD(11, 884) = 9724 / 9724

GCD(11, 884) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 585

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

LCM(1, 585) = 585

GCD(1, 585) = ( 1 x 585 ) / 585

GCD(1, 585) = 585 / 585

GCD(1, 585) = 1

GCD of 781, 660, 884, 585 is 1
