Given numbers are 489, 585, 215, 603
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 585) = 95355
GCD(489, 585) = ( 489 x 585 ) / 95355
= 489 / 585
= 489
Step2:
LCM(3, 215) = 645
GCD(3, 215) = ( 3 x 215 ) / 645
= 3 / 215
= 3
Step3:
LCM(1, 603) = 603
GCD(1, 603) = ( 1 x 603 ) / 603
= 1 / 603
= 1
So, Greatest Common Divisor of 489, 585, 215, 603 is 1
