Given Input Data is 392, 864, 619, 511

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

Prime Factorization of 392 is 2 x 2 x 2 x 7 x 7

Prime Factorization of 864 is 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime Factorization of 619 is 619

Prime Factorization of 511 is 7 x 73

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(392, 864) = 42336

GCD(392, 864) = ( 392 x 864 ) / 42336

GCD(392, 864) = 338688 / 42336

GCD(392, 864) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 619

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

LCM(8, 619) = 4952

GCD(8, 619) = ( 8 x 619 ) / 4952

GCD(8, 619) = 4952 / 4952

GCD(8, 619) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 511

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

LCM(1, 511) = 511

GCD(1, 511) = ( 1 x 511 ) / 511

GCD(1, 511) = 511 / 511

GCD(1, 511) = 1

GCD of 392, 864, 619, 511 is 1
