Given Input Data is 448, 511, 921, 435

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

Prime Factorization of 448 is 2 x 2 x 2 x 2 x 2 x 2 x 7

Prime Factorization of 511 is 7 x 73

Prime Factorization of 921 is 3 x 307

Prime Factorization of 435 is 3 x 5 x 29

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(448, 511) = 32704

GCD(448, 511) = ( 448 x 511 ) / 32704

GCD(448, 511) = 228928 / 32704

GCD(448, 511) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 921

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

LCM(7, 921) = 6447

GCD(7, 921) = ( 7 x 921 ) / 6447

GCD(7, 921) = 6447 / 6447

GCD(7, 921) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 435

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

LCM(1, 435) = 435

GCD(1, 435) = ( 1 x 435 ) / 435

GCD(1, 435) = 435 / 435

GCD(1, 435) = 1

GCD of 448, 511, 921, 435 is 1
