Given numbers are 686, 573, 805, 854

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(686, 573) = 393078

GCD(686, 573) = ( 686 x 573 ) / 393078

= 686 / 573

= 686

Step2:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

Step3:

LCM(1, 854) = 854

GCD(1, 854) = ( 1 x 854 ) / 854

= 1 / 854

= 1

So, Greatest Common Divisor of 686, 573, 805, 854 is 1
