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

Apply this formula for all numbers.

Step1:

LCM(986, 172) = 84796

GCD(986, 172) = ( 986 x 172 ) / 84796

= 986 / 172

= 986

Step2:

LCM(2, 866) = 866

GCD(2, 866) = ( 2 x 866 ) / 866

= 2 / 866

= 2

Step3:

LCM(2, 398) = 398

GCD(2, 398) = ( 2 x 398 ) / 398

= 2 / 398

= 2

So, Greatest Common Divisor of 986, 172, 866, 398 is 2
