Given numbers are 779, 287, 412, 209

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

Apply this formula for all numbers.

Step1:

LCM(779, 287) = 5453

GCD(779, 287) = ( 779 x 287 ) / 5453

= 779 / 287

= 779

Step2:

LCM(41, 412) = 16892

GCD(41, 412) = ( 41 x 412 ) / 16892

= 41 / 412

= 41

Step3:

LCM(1, 209) = 209

GCD(1, 209) = ( 1 x 209 ) / 209

= 1 / 209

= 1

So, Greatest Common Divisor of 779, 287, 412, 209 is 1
