Given numbers are 258, 478, 406, 797

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

Apply this formula for all numbers.

Step1:

LCM(258, 478) = 61662

GCD(258, 478) = ( 258 x 478 ) / 61662

= 258 / 478

= 258

Step2:

LCM(2, 406) = 406

GCD(2, 406) = ( 2 x 406 ) / 406

= 2 / 406

= 2

Step3:

LCM(2, 797) = 1594

GCD(2, 797) = ( 2 x 797 ) / 1594

= 2 / 797

= 2

So, Greatest Common Divisor of 258, 478, 406, 797 is 1
