Given numbers are 391, 255, 740, 789

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

Apply this formula for all numbers.

Step1:

LCM(391, 255) = 5865

GCD(391, 255) = ( 391 x 255 ) / 5865

= 391 / 255

= 391

Step2:

LCM(17, 740) = 12580

GCD(17, 740) = ( 17 x 740 ) / 12580

= 17 / 740

= 17

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 391, 255, 740, 789 is 1
