GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(979, 890) = 9790
GCD(979, 890) = ( 979 x 890 ) / 9790
= 979 / 890
= 979
Step2:
LCM(89, 195) = 17355
GCD(89, 195) = ( 89 x 195 ) / 17355
= 89 / 195
= 89
Step3:
LCM(1, 388) = 388
GCD(1, 388) = ( 1 x 388 ) / 388
= 1 / 388
= 1
So, Greatest Common Divisor of 979, 890, 195, 388 is 1
