Given numbers are 208, 489, 521

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

Apply this formula for all numbers.

Step1:

LCM(208, 489) = 101712

GCD(208, 489) = ( 208 x 489 ) / 101712

= 208 / 489

= 208

Step2:

LCM(1, 521) = 521

GCD(1, 521) = ( 1 x 521 ) / 521

= 1 / 521

= 1

So, Greatest Common Divisor of 208, 489, 521 is 1
