Given numbers are 911, 645, 789, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(911, 645) = 587595
GCD(911, 645) = ( 911 x 645 ) / 587595
= 911 / 645
= 911
Step2:
LCM(1, 789) = 789
GCD(1, 789) = ( 1 x 789 ) / 789
= 1 / 789
= 1
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 911, 645, 789, 815 is 1
