GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(489, 240) = 39120
GCD(489, 240) = ( 489 x 240 ) / 39120
= 489 / 240
= 489
Step2:
LCM(3, 180) = 180
GCD(3, 180) = ( 3 x 180 ) / 180
= 3 / 180
= 3
Step3:
LCM(3, 795) = 795
GCD(3, 795) = ( 3 x 795 ) / 795
= 3 / 795
= 3
So, Greatest Common Divisor of 489, 240, 180, 795 is 3
