GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 815) = 2445
GCD(489, 815) = ( 489 x 815 ) / 2445
= 489 / 815
= 489
Step2:
LCM(163, 493) = 80359
GCD(163, 493) = ( 163 x 493 ) / 80359
= 163 / 493
= 163
Step3:
LCM(1, 180) = 180
GCD(1, 180) = ( 1 x 180 ) / 180
= 1 / 180
= 1
So, Greatest Common Divisor of 489, 815, 493, 180 is 1
