Given numbers are 258, 480, 391, 460

The list of prime factors of all numbers are

Prime factors of 258 are 2 x 3 x 43

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 391 are 17 x 23

Prime factors of 460 are 2 x 2 x 5 x 23

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

Given numbers are 258, 480, 391, 460

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

Apply this formula for all numbers.

Step1:

LCM(258, 480) = 20640

GCD(258, 480) = ( 258 x 480 ) / 20640

= 258 / 480

= 258

Step2:

LCM(6, 391) = 2346

GCD(6, 391) = ( 6 x 391 ) / 2346

= 6 / 391

= 6

Step3:

LCM(1, 460) = 460

GCD(1, 460) = ( 1 x 460 ) / 460

= 1 / 460

= 1

So, Greatest Common Divisor of 258, 480, 391, 460 is 1
