Given Input Data is 840, 623, 313, 871

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

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 623 is 7 x 89

Prime Factorization of 313 is 313

Prime Factorization of 871 is 13 x 67

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(840, 623) = 74760

GCD(840, 623) = ( 840 x 623 ) / 74760

GCD(840, 623) = 523320 / 74760

GCD(840, 623) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 313

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

LCM(7, 313) = 2191

GCD(7, 313) = ( 7 x 313 ) / 2191

GCD(7, 313) = 2191 / 2191

GCD(7, 313) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 871

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

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

GCD(1, 871) = 871 / 871

GCD(1, 871) = 1

GCD of 840, 623, 313, 871 is 1
