Given numbers are 621, 489, 59, 278

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

Apply this formula for all numbers.

Step1:

LCM(621, 489) = 101223

GCD(621, 489) = ( 621 x 489 ) / 101223

= 621 / 489

= 621

Step2:

LCM(3, 59) = 177

GCD(3, 59) = ( 3 x 59 ) / 177

= 3 / 59

= 3

Step3:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

So, Greatest Common Divisor of 621, 489, 59, 278 is 1
