Given numbers are 489, 492, 178

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

Apply this formula for all numbers.

Step1:

LCM(489, 492) = 80196

GCD(489, 492) = ( 489 x 492 ) / 80196

= 489 / 492

= 489

Step2:

LCM(3, 178) = 534

GCD(3, 178) = ( 3 x 178 ) / 534

= 3 / 178

= 3

So, Greatest Common Divisor of 489, 492, 178 is 1
