Given numbers are 819, 581, 291, 669

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

Apply this formula for all numbers.

Step1:

LCM(819, 581) = 67977

GCD(819, 581) = ( 819 x 581 ) / 67977

= 819 / 581

= 819

Step2:

LCM(7, 291) = 2037

GCD(7, 291) = ( 7 x 291 ) / 2037

= 7 / 291

= 7

Step3:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

So, Greatest Common Divisor of 819, 581, 291, 669 is 1
