Given numbers are 273, 945, 639, 191

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

Apply this formula for all numbers.

Step1:

LCM(273, 945) = 12285

GCD(273, 945) = ( 273 x 945 ) / 12285

= 273 / 945

= 273

Step2:

LCM(21, 639) = 4473

GCD(21, 639) = ( 21 x 639 ) / 4473

= 21 / 639

= 21

Step3:

LCM(3, 191) = 573

GCD(3, 191) = ( 3 x 191 ) / 573

= 3 / 191

= 3

So, Greatest Common Divisor of 273, 945, 639, 191 is 1
