GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 396) = 32868
GCD(747, 396) = ( 747 x 396 ) / 32868
= 747 / 396
= 747
Step2:
LCM(9, 168) = 504
GCD(9, 168) = ( 9 x 168 ) / 504
= 9 / 168
= 9
Step3:
LCM(3, 819) = 819
GCD(3, 819) = ( 3 x 819 ) / 819
= 3 / 819
= 3
So, Greatest Common Divisor of 747, 396, 168, 819 is 3
