Given numbers are 518, 891, 317, 809
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(518, 891) = 461538
GCD(518, 891) = ( 518 x 891 ) / 461538
= 518 / 891
= 518
Step2:
LCM(1, 317) = 317
GCD(1, 317) = ( 1 x 317 ) / 317
= 1 / 317
= 1
Step3:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
So, Greatest Common Divisor of 518, 891, 317, 809 is 1
