Given numbers are 866, 980, 390, 194

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

Apply this formula for all numbers.

Step1:

LCM(866, 980) = 424340

GCD(866, 980) = ( 866 x 980 ) / 424340

= 866 / 980

= 866

Step2:

LCM(2, 390) = 390

GCD(2, 390) = ( 2 x 390 ) / 390

= 2 / 390

= 2

Step3:

LCM(2, 194) = 194

GCD(2, 194) = ( 2 x 194 ) / 194

= 2 / 194

= 2

So, Greatest Common Divisor of 866, 980, 390, 194 is 2
