Given Input Data is 648, 711, 89, 578

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

Prime Factorization of 648 is 2 x 2 x 2 x 3 x 3 x 3 x 3

Prime Factorization of 711 is 3 x 3 x 79

Prime Factorization of 89 is 89

Prime Factorization of 578 is 2 x 17 x 17

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(648, 711) = 51192

GCD(648, 711) = ( 648 x 711 ) / 51192

GCD(648, 711) = 460728 / 51192

GCD(648, 711) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 89

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

LCM(9, 89) = 801

GCD(9, 89) = ( 9 x 89 ) / 801

GCD(9, 89) = 801 / 801

GCD(9, 89) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 578

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

LCM(1, 578) = 578

GCD(1, 578) = ( 1 x 578 ) / 578

GCD(1, 578) = 578 / 578

GCD(1, 578) = 1

GCD of 648, 711, 89, 578 is 1
