Given numbers are 489, 660, 556, 716

The list of prime factors of all numbers are

Prime factors of 489 are 3 x 163

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 556 are 2 x 2 x 139

Prime factors of 716 are 2 x 2 x 179

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

Given numbers are 489, 660, 556, 716

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

Apply this formula for all numbers.

Step1:

LCM(489, 660) = 107580

GCD(489, 660) = ( 489 x 660 ) / 107580

= 489 / 660

= 489

Step2:

LCM(3, 556) = 1668

GCD(3, 556) = ( 3 x 556 ) / 1668

= 3 / 556

= 3

Step3:

LCM(1, 716) = 716

GCD(1, 716) = ( 1 x 716 ) / 716

= 1 / 716

= 1

So, Greatest Common Divisor of 489, 660, 556, 716 is 1
