Given numbers are 489, 691, 125, 276

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

Apply this formula for all numbers.

Step1:

LCM(489, 691) = 337899

GCD(489, 691) = ( 489 x 691 ) / 337899

= 489 / 691

= 489

Step2:

LCM(1, 125) = 125

GCD(1, 125) = ( 1 x 125 ) / 125

= 1 / 125

= 1

Step3:

LCM(1, 276) = 276

GCD(1, 276) = ( 1 x 276 ) / 276

= 1 / 276

= 1

So, Greatest Common Divisor of 489, 691, 125, 276 is 1
