Given Input Data is 440, 385, 817, 877

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 385 is 5 x 7 x 11

Prime Factorization of 817 is 19 x 43

Prime Factorization of 877 is 877

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, 385) = 3080

GCD(440, 385) = ( 440 x 385 ) / 3080

GCD(440, 385) = 169400 / 3080

GCD(440, 385) = 55

Step2:

Here we consider the GCD from the above i.e. 55 as first number and the next as 817

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

LCM(55, 817) = 44935

GCD(55, 817) = ( 55 x 817 ) / 44935

GCD(55, 817) = 44935 / 44935

GCD(55, 817) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 877

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

LCM(1, 877) = 877

GCD(1, 877) = ( 1 x 877 ) / 877

GCD(1, 877) = 877 / 877

GCD(1, 877) = 1

GCD of 440, 385, 817, 877 is 1
