Given numbers are 819, 222, 795, 781

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

Apply this formula for all numbers.

Step1:

LCM(819, 222) = 60606

GCD(819, 222) = ( 819 x 222 ) / 60606

= 819 / 222

= 819

Step2:

LCM(3, 795) = 795

GCD(3, 795) = ( 3 x 795 ) / 795

= 3 / 795

= 3

Step3:

LCM(3, 781) = 2343

GCD(3, 781) = ( 3 x 781 ) / 2343

= 3 / 781

= 3

So, Greatest Common Divisor of 819, 222, 795, 781 is 1
