Given numbers are 668, 829, 930, 686

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(668, 829) = 553772

GCD(668, 829) = ( 668 x 829 ) / 553772

= 668 / 829

= 668

Step2:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 668, 829, 930, 686 is 1
