Given numbers are 205, 768, 200, 489

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime factors of 200 are 2 x 2 x 2 x 5 x 5

Prime factors of 489 are 3 x 163

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

Given numbers are 205, 768, 200, 489

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

Apply this formula for all numbers.

Step1:

LCM(205, 768) = 157440

GCD(205, 768) = ( 205 x 768 ) / 157440

= 205 / 768

= 205

Step2:

LCM(1, 200) = 200

GCD(1, 200) = ( 1 x 200 ) / 200

= 1 / 200

= 1

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 205, 768, 200, 489 is 1
