Given numbers are 478, 346, 774, 489

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

Apply this formula for all numbers.

Step1:

LCM(478, 346) = 82694

GCD(478, 346) = ( 478 x 346 ) / 82694

= 478 / 346

= 478

Step2:

LCM(2, 774) = 774

GCD(2, 774) = ( 2 x 774 ) / 774

= 2 / 774

= 2

Step3:

LCM(2, 489) = 978

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

= 2 / 489

= 2

So, Greatest Common Divisor of 478, 346, 774, 489 is 1
