Given numbers are 723, 912, 677, 489
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(723, 912) = 219792
GCD(723, 912) = ( 723 x 912 ) / 219792
= 723 / 912
= 723
Step2:
LCM(3, 677) = 2031
GCD(3, 677) = ( 3 x 677 ) / 2031
= 3 / 677
= 3
Step3:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
So, Greatest Common Divisor of 723, 912, 677, 489 is 1
