Given numbers are 489, 395, 225, 853

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

Apply this formula for all numbers.

Step1:

LCM(489, 395) = 193155

GCD(489, 395) = ( 489 x 395 ) / 193155

= 489 / 395

= 489

Step2:

LCM(1, 225) = 225

GCD(1, 225) = ( 1 x 225 ) / 225

= 1 / 225

= 1

Step3:

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

= 1 / 853

= 1

So, Greatest Common Divisor of 489, 395, 225, 853 is 1
