GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 556) = 108420
GCD(390, 556) = ( 390 x 556 ) / 108420
= 390 / 556
= 390
Step2:
LCM(2, 568) = 568
GCD(2, 568) = ( 2 x 568 ) / 568
= 2 / 568
= 2
Step3:
LCM(2, 996) = 996
GCD(2, 996) = ( 2 x 996 ) / 996
= 2 / 996
= 2
So, Greatest Common Divisor of 390, 556, 568, 996 is 2
