GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(816, 840) = 28560
GCD(816, 840) = ( 816 x 840 ) / 28560
= 816 / 840
= 816
Step2:
LCM(24, 605) = 14520
GCD(24, 605) = ( 24 x 605 ) / 14520
= 24 / 605
= 24
So, Greatest Common Divisor of 816, 840, 605 is 1
