Given numbers are 205, 720, 818, 204

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 818 are 2 x 409

Prime factors of 204 are 2 x 2 x 3 x 17

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 205, 720, 818, 204

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(205, 720) = 29520

GCD(205, 720) = ( 205 x 720 ) / 29520

= 205 / 720

= 205

Step2:

LCM(5, 818) = 4090

GCD(5, 818) = ( 5 x 818 ) / 4090

= 5 / 818

= 5

Step3:

LCM(1, 204) = 204

GCD(1, 204) = ( 1 x 204 ) / 204

= 1 / 204

= 1

So, Greatest Common Divisor of 205, 720, 818, 204 is 1
