Given Input Data is 646, 399, 23, 882

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

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 399 is 3 x 7 x 19

Prime Factorization of 23 is 23

Prime Factorization of 882 is 2 x 3 x 3 x 7 x 7

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(646, 399) = 13566

GCD(646, 399) = ( 646 x 399 ) / 13566

GCD(646, 399) = 257754 / 13566

GCD(646, 399) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 23

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

LCM(19, 23) = 437

GCD(19, 23) = ( 19 x 23 ) / 437

GCD(19, 23) = 437 / 437

GCD(19, 23) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 882

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

LCM(1, 882) = 882

GCD(1, 882) = ( 1 x 882 ) / 882

GCD(1, 882) = 882 / 882

GCD(1, 882) = 1

GCD of 646, 399, 23, 882 is 1
