Given numbers are 819, 768, 783, 842

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

Apply this formula for all numbers.

Step1:

LCM(819, 768) = 209664

GCD(819, 768) = ( 819 x 768 ) / 209664

= 819 / 768

= 819

Step2:

LCM(3, 783) = 783

GCD(3, 783) = ( 3 x 783 ) / 783

= 3 / 783

= 3

Step3:

LCM(3, 842) = 2526

GCD(3, 842) = ( 3 x 842 ) / 2526

= 3 / 842

= 3

So, Greatest Common Divisor of 819, 768, 783, 842 is 1
