Given numbers are 258, 840, 771, 478

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 771 are 3 x 257

Prime factors of 478 are 2 x 239

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 258, 840, 771, 478

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

Apply this formula for all numbers.

Step1:

LCM(258, 840) = 36120

GCD(258, 840) = ( 258 x 840 ) / 36120

= 258 / 840

= 258

Step2:

LCM(6, 771) = 1542

GCD(6, 771) = ( 6 x 771 ) / 1542

= 6 / 771

= 6

Step3:

LCM(3, 478) = 1434

GCD(3, 478) = ( 3 x 478 ) / 1434

= 3 / 478

= 3

So, Greatest Common Divisor of 258, 840, 771, 478 is 1
