Given numbers are 489, 210, 725, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 210) = 34230
GCD(489, 210) = ( 489 x 210 ) / 34230
= 489 / 210
= 489
Step2:
LCM(3, 725) = 2175
GCD(3, 725) = ( 3 x 725 ) / 2175
= 3 / 725
= 3
Step3:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
So, Greatest Common Divisor of 489, 210, 725, 485 is 1
