Given numbers are 779, 494, 49, 489

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

Apply this formula for all numbers.

Step1:

LCM(779, 494) = 20254

GCD(779, 494) = ( 779 x 494 ) / 20254

= 779 / 494

= 779

Step2:

LCM(19, 49) = 931

GCD(19, 49) = ( 19 x 49 ) / 931

= 19 / 49

= 19

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 779, 494, 49, 489 is 1
