Therefore, GCD of numbers 620, 820, 817, 480 is 1

Given Input Data is 620, 820, 817, 480

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

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 820 is 2 x 2 x 5 x 41

Prime Factorization of 817 is 19 x 43

Prime Factorization of 480 is 2 x 2 x 2 x 2 x 2 x 3 x 5

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(620, 820) = 25420

GCD(620, 820) = ( 620 x 820 ) / 25420

GCD(620, 820) = 508400 / 25420

GCD(620, 820) = 20

Step2:

Here we consider the GCD from the above i.e. 20 as first number and the next as 817

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

LCM(20, 817) = 16340

GCD(20, 817) = ( 20 x 817 ) / 16340

GCD(20, 817) = 16340 / 16340

GCD(20, 817) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 480

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

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

GCD(1, 480) = 480 / 480

GCD(1, 480) = 1

GCD of 620, 820, 817, 480 is 1
