Given numbers are 258, 897, 556, 286

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

Apply this formula for all numbers.

Step1:

LCM(258, 897) = 77142

GCD(258, 897) = ( 258 x 897 ) / 77142

= 258 / 897

= 258

Step2:

LCM(3, 556) = 1668

GCD(3, 556) = ( 3 x 556 ) / 1668

= 3 / 556

= 3

Step3:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

So, Greatest Common Divisor of 258, 897, 556, 286 is 1
