GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(693, 891) = 6237
GCD(693, 891) = ( 693 x 891 ) / 6237
= 693 / 891
= 693
Step2:
LCM(99, 858) = 2574
GCD(99, 858) = ( 99 x 858 ) / 2574
= 99 / 858
= 99
Step3:
LCM(33, 779) = 25707
GCD(33, 779) = ( 33 x 779 ) / 25707
= 33 / 779
= 33
So, Greatest Common Divisor of 693, 891, 858, 779 is 1
