GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(862, 390) = 168090
GCD(862, 390) = ( 862 x 390 ) / 168090
= 862 / 390
= 862
Step2:
LCM(2, 398) = 398
GCD(2, 398) = ( 2 x 398 ) / 398
= 2 / 398
= 2
Step3:
LCM(2, 406) = 406
GCD(2, 406) = ( 2 x 406 ) / 406
= 2 / 406
= 2
So, Greatest Common Divisor of 862, 390, 398, 406 is 2
