Given Input Data is 440, 803, 311, 660

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

Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11

Prime Factorization of 803 is 11 x 73

Prime Factorization of 311 is 311

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

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(440, 803) = 32120

GCD(440, 803) = ( 440 x 803 ) / 32120

GCD(440, 803) = 353320 / 32120

GCD(440, 803) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 311

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

LCM(11, 311) = 3421

GCD(11, 311) = ( 11 x 311 ) / 3421

GCD(11, 311) = 3421 / 3421

GCD(11, 311) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 660

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

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

GCD(1, 660) = 660 / 660

GCD(1, 660) = 1

GCD of 440, 803, 311, 660 is 1
