Given numbers are 159, 686, 230, 391
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(159, 686) = 109074
GCD(159, 686) = ( 159 x 686 ) / 109074
= 159 / 686
= 159
Step2:
LCM(1, 230) = 230
GCD(1, 230) = ( 1 x 230 ) / 230
= 1 / 230
= 1
Step3:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
So, Greatest Common Divisor of 159, 686, 230, 391 is 1
