Given numbers are 779, 285, 42, 342

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

Apply this formula for all numbers.

Step1:

LCM(779, 285) = 11685

GCD(779, 285) = ( 779 x 285 ) / 11685

= 779 / 285

= 779

Step2:

LCM(19, 42) = 798

GCD(19, 42) = ( 19 x 42 ) / 798

= 19 / 42

= 19

Step3:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

So, Greatest Common Divisor of 779, 285, 42, 342 is 1
