Given numbers are 537, 840, 390, 819

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

Apply this formula for all numbers.

Step1:

LCM(537, 840) = 150360

GCD(537, 840) = ( 537 x 840 ) / 150360

= 537 / 840

= 537

Step2:

LCM(3, 390) = 390

GCD(3, 390) = ( 3 x 390 ) / 390

= 3 / 390

= 3

Step3:

LCM(3, 819) = 819

GCD(3, 819) = ( 3 x 819 ) / 819

= 3 / 819

= 3

So, Greatest Common Divisor of 537, 840, 390, 819 is 3
