Given numbers are 819, 291, 249, 790

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

Apply this formula for all numbers.

Step1:

LCM(819, 291) = 79443

GCD(819, 291) = ( 819 x 291 ) / 79443

= 819 / 291

= 819

Step2:

LCM(3, 249) = 249

GCD(3, 249) = ( 3 x 249 ) / 249

= 3 / 249

= 3

Step3:

LCM(3, 790) = 2370

GCD(3, 790) = ( 3 x 790 ) / 2370

= 3 / 790

= 3

So, Greatest Common Divisor of 819, 291, 249, 790 is 1
