Given numbers are 869, 391, 108

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

Apply this formula for all numbers.

Step1:

LCM(869, 391) = 339779

GCD(869, 391) = ( 869 x 391 ) / 339779

= 869 / 391

= 869

Step2:

LCM(1, 108) = 108

GCD(1, 108) = ( 1 x 108 ) / 108

= 1 / 108

= 1

So, Greatest Common Divisor of 869, 391, 108 is 1
