Given numbers are 257, 602, 556, 858

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 602 are 2 x 7 x 43

Prime factors of 556 are 2 x 2 x 139

Prime factors of 858 are 2 x 3 x 11 x 13

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

Given numbers are 257, 602, 556, 858

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

Apply this formula for all numbers.

Step1:

LCM(257, 602) = 154714

GCD(257, 602) = ( 257 x 602 ) / 154714

= 257 / 602

= 257

Step2:

LCM(1, 556) = 556

GCD(1, 556) = ( 1 x 556 ) / 556

= 1 / 556

= 1

Step3:

LCM(1, 858) = 858

GCD(1, 858) = ( 1 x 858 ) / 858

= 1 / 858

= 1

So, Greatest Common Divisor of 257, 602, 556, 858 is 1
