Therefore, GCD of numbers 780, 510, 163, 396 is 1

Given Input Data is 780, 510, 163, 396

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

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 510 is 2 x 3 x 5 x 17

Prime Factorization of 163 is 163

Prime Factorization of 396 is 2 x 2 x 3 x 3 x 11

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(780, 510) = 13260

GCD(780, 510) = ( 780 x 510 ) / 13260

GCD(780, 510) = 397800 / 13260

GCD(780, 510) = 30

Step2:

Here we consider the GCD from the above i.e. 30 as first number and the next as 163

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

LCM(30, 163) = 4890

GCD(30, 163) = ( 30 x 163 ) / 4890

GCD(30, 163) = 4890 / 4890

GCD(30, 163) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 396

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

LCM(1, 396) = 396

GCD(1, 396) = ( 1 x 396 ) / 396

GCD(1, 396) = 396 / 396

GCD(1, 396) = 1

GCD of 780, 510, 163, 396 is 1
