GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 606) = 207858
GCD(686, 606) = ( 686 x 606 ) / 207858
= 686 / 606
= 686
Step2:
LCM(2, 446) = 446
GCD(2, 446) = ( 2 x 446 ) / 446
= 2 / 446
= 2
Step3:
LCM(2, 818) = 818
GCD(2, 818) = ( 2 x 818 ) / 818
= 2 / 818
= 2
So, Greatest Common Divisor of 686, 606, 446, 818 is 2
