Given numbers are 128, 107, 391

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

Apply this formula for all numbers.

Step1:

LCM(128, 107) = 13696

GCD(128, 107) = ( 128 x 107 ) / 13696

= 128 / 107

= 128

Step2:

LCM(1, 391) = 391

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

= 1 / 391

= 1

So, Greatest Common Divisor of 128, 107, 391 is 1
