Given Input Data is 390, 753, 534, 865

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

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 753 is 3 x 251

Prime Factorization of 534 is 2 x 3 x 89

Prime Factorization of 865 is 5 x 173

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(390, 753) = 97890

GCD(390, 753) = ( 390 x 753 ) / 97890

GCD(390, 753) = 293670 / 97890

GCD(390, 753) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 534

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

LCM(3, 534) = 534

GCD(3, 534) = ( 3 x 534 ) / 534

GCD(3, 534) = 1602 / 534

GCD(3, 534) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 865

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

LCM(3, 865) = 2595

GCD(3, 865) = ( 3 x 865 ) / 2595

GCD(3, 865) = 2595 / 2595

GCD(3, 865) = 1

GCD of 390, 753, 534, 865 is 1
