Given numbers are 556, 768, 489, 309

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

Apply this formula for all numbers.

Step1:

LCM(556, 768) = 106752

GCD(556, 768) = ( 556 x 768 ) / 106752

= 556 / 768

= 556

Step2:

LCM(4, 489) = 1956

GCD(4, 489) = ( 4 x 489 ) / 1956

= 4 / 489

= 4

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 556, 768, 489, 309 is 1
