GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 686) = 288806
GCD(842, 686) = ( 842 x 686 ) / 288806
= 842 / 686
= 842
Step2:
LCM(2, 310) = 310
GCD(2, 310) = ( 2 x 310 ) / 310
= 2 / 310
= 2
Step3:
LCM(2, 256) = 256
GCD(2, 256) = ( 2 x 256 ) / 256
= 2 / 256
= 2
So, Greatest Common Divisor of 842, 686, 310, 256 is 2
