Given numbers are 250, 855, 657, 257

The list of prime factors of all numbers are

Prime factors of 250 are 2 x 5 x 5 x 5

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 657 are 3 x 3 x 73

Prime factors of 257 are 257

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

Given numbers are 250, 855, 657, 257

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

Apply this formula for all numbers.

Step1:

LCM(250, 855) = 42750

GCD(250, 855) = ( 250 x 855 ) / 42750

= 250 / 855

= 250

Step2:

LCM(5, 657) = 3285

GCD(5, 657) = ( 5 x 657 ) / 3285

= 5 / 657

= 5

Step3:

LCM(1, 257) = 257

GCD(1, 257) = ( 1 x 257 ) / 257

= 1 / 257

= 1

So, Greatest Common Divisor of 250, 855, 657, 257 is 1
