Given numbers are 843, 431, 855

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

Apply this formula for all numbers.

Step1:

LCM(843, 431) = 363333

GCD(843, 431) = ( 843 x 431 ) / 363333

= 843 / 431

= 843

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 843, 431, 855 is 1
