Given numbers are 489, 495, 891, 974

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

Apply this formula for all numbers.

Step1:

LCM(489, 495) = 80685

GCD(489, 495) = ( 489 x 495 ) / 80685

= 489 / 495

= 489

Step2:

LCM(3, 891) = 891

GCD(3, 891) = ( 3 x 891 ) / 891

= 3 / 891

= 3

Step3:

LCM(3, 974) = 2922

GCD(3, 974) = ( 3 x 974 ) / 2922

= 3 / 974

= 3

So, Greatest Common Divisor of 489, 495, 891, 974 is 1
