Given numbers are 258, 389, 85

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

Apply this formula for all numbers.

Step1:

LCM(258, 389) = 100362

GCD(258, 389) = ( 258 x 389 ) / 100362

= 258 / 389

= 258

Step2:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1

So, Greatest Common Divisor of 258, 389, 85 is 1
