Given numbers are 658, 489, 580, 277

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

Apply this formula for all numbers.

Step1:

LCM(658, 489) = 321762

GCD(658, 489) = ( 658 x 489 ) / 321762

= 658 / 489

= 658

Step2:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

Step3:

LCM(1, 277) = 277

GCD(1, 277) = ( 1 x 277 ) / 277

= 1 / 277

= 1

So, Greatest Common Divisor of 658, 489, 580, 277 is 1
