GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(742, 809) = 600278
GCD(742, 809) = ( 742 x 809 ) / 600278
= 742 / 809
= 742
Step2:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 742, 809, 489, 891 is 1
