Given numbers are 861, 903, 809, 194

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

Apply this formula for all numbers.

Step1:

LCM(861, 903) = 37023

GCD(861, 903) = ( 861 x 903 ) / 37023

= 861 / 903

= 861

Step2:

LCM(21, 809) = 16989

GCD(21, 809) = ( 21 x 809 ) / 16989

= 21 / 809

= 21

Step3:

LCM(1, 194) = 194

GCD(1, 194) = ( 1 x 194 ) / 194

= 1 / 194

= 1

So, Greatest Common Divisor of 861, 903, 809, 194 is 1
