Given numbers are 512, 657, 391

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

Apply this formula for all numbers.

Step1:

LCM(512, 657) = 336384

GCD(512, 657) = ( 512 x 657 ) / 336384

= 512 / 657

= 512

Step2:

LCM(1, 391) = 391

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

= 1 / 391

= 1

So, Greatest Common Divisor of 512, 657, 391 is 1
