Given numbers are 489, 320, 971, 943

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

Apply this formula for all numbers.

Step1:

LCM(489, 320) = 156480

GCD(489, 320) = ( 489 x 320 ) / 156480

= 489 / 320

= 489

Step2:

LCM(1, 971) = 971

GCD(1, 971) = ( 1 x 971 ) / 971

= 1 / 971

= 1

Step3:

LCM(1, 943) = 943

GCD(1, 943) = ( 1 x 943 ) / 943

= 1 / 943

= 1

So, Greatest Common Divisor of 489, 320, 971, 943 is 1
