Given numbers are 720, 489, 939, 206

The list of prime factors of all numbers are

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

Prime factors of 489 are 3 x 163

Prime factors of 939 are 3 x 313

Prime factors of 206 are 2 x 103

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

Given numbers are 720, 489, 939, 206

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

Apply this formula for all numbers.

Step1:

LCM(720, 489) = 117360

GCD(720, 489) = ( 720 x 489 ) / 117360

= 720 / 489

= 720

Step2:

LCM(3, 939) = 939

GCD(3, 939) = ( 3 x 939 ) / 939

= 3 / 939

= 3

Step3:

LCM(3, 206) = 618

GCD(3, 206) = ( 3 x 206 ) / 618

= 3 / 206

= 3

So, Greatest Common Divisor of 720, 489, 939, 206 is 1
