Given numbers are 778, 266, 489

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

Apply this formula for all numbers.

Step1:

LCM(778, 266) = 103474

GCD(778, 266) = ( 778 x 266 ) / 103474

= 778 / 266

= 778

Step2:

LCM(2, 489) = 978

GCD(2, 489) = ( 2 x 489 ) / 978

= 2 / 489

= 2

So, Greatest Common Divisor of 778, 266, 489 is 1
