Given Input Data is 390, 440, 963, 885

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 440 is 2 x 2 x 2 x 5 x 11

Prime Factorization of 963 is 3 x 3 x 107

Prime Factorization of 885 is 3 x 5 x 59

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, 440) = 17160

GCD(390, 440) = ( 390 x 440 ) / 17160

GCD(390, 440) = 171600 / 17160

GCD(390, 440) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 963

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

LCM(10, 963) = 9630

GCD(10, 963) = ( 10 x 963 ) / 9630

GCD(10, 963) = 9630 / 9630

GCD(10, 963) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 885

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

LCM(1, 885) = 885

GCD(1, 885) = ( 1 x 885 ) / 885

GCD(1, 885) = 885 / 885

GCD(1, 885) = 1

GCD of 390, 440, 963, 885 is 1
