Given numbers are 549, 756, 447, 308

The list of prime factors of all numbers are

Prime factors of 549 are 3 x 3 x 61

Prime factors of 756 are 2 x 2 x 3 x 3 x 3 x 7

Prime factors of 447 are 3 x 149

Prime factors of 308 are 2 x 2 x 7 x 11

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

Given numbers are 549, 756, 447, 308

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

Apply this formula for all numbers.

Step1:

LCM(549, 756) = 46116

GCD(549, 756) = ( 549 x 756 ) / 46116

= 549 / 756

= 549

Step2:

LCM(9, 447) = 1341

GCD(9, 447) = ( 9 x 447 ) / 1341

= 9 / 447

= 9

Step3:

LCM(3, 308) = 924

GCD(3, 308) = ( 3 x 308 ) / 924

= 3 / 308

= 3

So, Greatest Common Divisor of 549, 756, 447, 308 is 1
