Given numbers are 258, 629, 391

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

Apply this formula for all numbers.

Step1:

LCM(258, 629) = 162282

GCD(258, 629) = ( 258 x 629 ) / 162282

= 258 / 629

= 258

Step2:

LCM(1, 391) = 391

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

= 1 / 391

= 1

So, Greatest Common Divisor of 258, 629, 391 is 1
