Given Input Data is 437, 988, 13

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

Prime Factorization of 437 is 19 x 23

Prime Factorization of 988 is 2 x 2 x 13 x 19

Prime Factorization of 13 is 13

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(437, 988) = 22724

GCD(437, 988) = ( 437 x 988 ) / 22724

GCD(437, 988) = 431756 / 22724

GCD(437, 988) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 13

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

LCM(19, 13) = 247

GCD(19, 13) = ( 19 x 13 ) / 247

GCD(19, 13) = 247 / 247

GCD(19, 13) = 1

GCD of 437, 988, 13 is 1
