Given numbers are 809, 786, 654, 517
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(809, 786) = 635874
GCD(809, 786) = ( 809 x 786 ) / 635874
= 809 / 786
= 809
Step2:
LCM(1, 654) = 654
GCD(1, 654) = ( 1 x 654 ) / 654
= 1 / 654
= 1
Step3:
LCM(1, 517) = 517
GCD(1, 517) = ( 1 x 517 ) / 517
= 1 / 517
= 1
So, Greatest Common Divisor of 809, 786, 654, 517 is 1
