Given numbers are 855, 789, 452, 391

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

Apply this formula for all numbers.

Step1:

LCM(855, 789) = 224865

GCD(855, 789) = ( 855 x 789 ) / 224865

= 855 / 789

= 855

Step2:

LCM(3, 452) = 1356

GCD(3, 452) = ( 3 x 452 ) / 1356

= 3 / 452

= 3

Step3:

LCM(1, 391) = 391

GCD(1, 391) = ( 1 x 391 ) / 391

= 1 / 391

= 1

So, Greatest Common Divisor of 855, 789, 452, 391 is 1
