Given numbers are 838, 662, 778, 819

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

Apply this formula for all numbers.

Step1:

LCM(838, 662) = 277378

GCD(838, 662) = ( 838 x 662 ) / 277378

= 838 / 662

= 838

Step2:

LCM(2, 778) = 778

GCD(2, 778) = ( 2 x 778 ) / 778

= 2 / 778

= 2

Step3:

LCM(2, 819) = 1638

GCD(2, 819) = ( 2 x 819 ) / 1638

= 2 / 819

= 2

So, Greatest Common Divisor of 838, 662, 778, 819 is 1
