Given numbers are 489, 902, 339, 821

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

Apply this formula for all numbers.

Step1:

LCM(489, 902) = 441078

GCD(489, 902) = ( 489 x 902 ) / 441078

= 489 / 902

= 489

Step2:

LCM(1, 339) = 339

GCD(1, 339) = ( 1 x 339 ) / 339

= 1 / 339

= 1

Step3:

LCM(1, 821) = 821

GCD(1, 821) = ( 1 x 821 ) / 821

= 1 / 821

= 1

So, Greatest Common Divisor of 489, 902, 339, 821 is 1
