GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 153) = 13923
GCD(819, 153) = ( 819 x 153 ) / 13923
= 819 / 153
= 819
Step2:
LCM(9, 708) = 2124
GCD(9, 708) = ( 9 x 708 ) / 2124
= 9 / 708
= 9
Step3:
LCM(3, 459) = 459
GCD(3, 459) = ( 3 x 459 ) / 459
= 3 / 459
= 3
So, Greatest Common Divisor of 819, 153, 708, 459 is 3
