Given Input Data is 768, 520, 801, 711

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

Prime Factorization of 768 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Prime Factorization of 801 is 3 x 3 x 89

Prime Factorization of 711 is 3 x 3 x 79

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(768, 520) = 49920

GCD(768, 520) = ( 768 x 520 ) / 49920

GCD(768, 520) = 399360 / 49920

GCD(768, 520) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 801

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

LCM(8, 801) = 6408

GCD(8, 801) = ( 8 x 801 ) / 6408

GCD(8, 801) = 6408 / 6408

GCD(8, 801) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 711

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

LCM(1, 711) = 711

GCD(1, 711) = ( 1 x 711 ) / 711

GCD(1, 711) = 711 / 711

GCD(1, 711) = 1

GCD of 768, 520, 801, 711 is 1
