Given numbers are 404, 665, 686, 239
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(404, 665) = 268660
GCD(404, 665) = ( 404 x 665 ) / 268660
= 404 / 665
= 404
Step2:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
Step3:
LCM(1, 239) = 239
GCD(1, 239) = ( 1 x 239 ) / 239
= 1 / 239
= 1
So, Greatest Common Divisor of 404, 665, 686, 239 is 1
