GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 408) = 7752
GCD(646, 408) = ( 646 x 408 ) / 7752
= 646 / 408
= 646
Step2:
LCM(34, 622) = 10574
GCD(34, 622) = ( 34 x 622 ) / 10574
= 34 / 622
= 34
Step3:
LCM(2, 806) = 806
GCD(2, 806) = ( 2 x 806 ) / 806
= 2 / 806
= 2
So, Greatest Common Divisor of 646, 408, 622, 806 is 2
