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
