Given numbers are 819, 189, 847, 726

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

Apply this formula for all numbers.

Step1:

LCM(819, 189) = 2457

GCD(819, 189) = ( 819 x 189 ) / 2457

= 819 / 189

= 819

Step2:

LCM(63, 847) = 7623

GCD(63, 847) = ( 63 x 847 ) / 7623

= 63 / 847

= 63

Step3:

LCM(7, 726) = 5082

GCD(7, 726) = ( 7 x 726 ) / 5082

= 7 / 726

= 7

So, Greatest Common Divisor of 819, 189, 847, 726 is 1
