Given numbers are 549, 948, 959, 645

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

Apply this formula for all numbers.

Step1:

LCM(549, 948) = 173484

GCD(549, 948) = ( 549 x 948 ) / 173484

= 549 / 948

= 549

Step2:

LCM(3, 959) = 2877

GCD(3, 959) = ( 3 x 959 ) / 2877

= 3 / 959

= 3

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 549, 948, 959, 645 is 1
