GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 789) = 616209
GCD(781, 789) = ( 781 x 789 ) / 616209
= 781 / 789
= 781
Step2:
LCM(1, 961) = 961
GCD(1, 961) = ( 1 x 961 ) / 961
= 1 / 961
= 1
Step3:
LCM(1, 893) = 893
GCD(1, 893) = ( 1 x 893 ) / 893
= 1 / 893
= 1
So, Greatest Common Divisor of 781, 789, 961, 893 is 1
