Given numbers are 258, 638, 870, 568

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

Apply this formula for all numbers.

Step1:

LCM(258, 638) = 82302

GCD(258, 638) = ( 258 x 638 ) / 82302

= 258 / 638

= 258

Step2:

LCM(2, 870) = 870

GCD(2, 870) = ( 2 x 870 ) / 870

= 2 / 870

= 2

Step3:

LCM(2, 568) = 568

GCD(2, 568) = ( 2 x 568 ) / 568

= 2 / 568

= 2

So, Greatest Common Divisor of 258, 638, 870, 568 is 2
