Given numbers are 309, 915, 548, 189

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

Apply this formula for all numbers.

Step1:

LCM(309, 915) = 94245

GCD(309, 915) = ( 309 x 915 ) / 94245

= 309 / 915

= 309

Step2:

LCM(3, 548) = 1644

GCD(3, 548) = ( 3 x 548 ) / 1644

= 3 / 548

= 3

Step3:

LCM(1, 189) = 189

GCD(1, 189) = ( 1 x 189 ) / 189

= 1 / 189

= 1

So, Greatest Common Divisor of 309, 915, 548, 189 is 1
