Given numbers are 257, 100, 515, 164

The list of prime factors of all numbers are

Prime factors of 257 are 257

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 515 are 5 x 103

Prime factors of 164 are 2 x 2 x 41

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

Given numbers are 257, 100, 515, 164

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

Apply this formula for all numbers.

Step1:

LCM(257, 100) = 25700

GCD(257, 100) = ( 257 x 100 ) / 25700

= 257 / 100

= 257

Step2:

LCM(1, 515) = 515

GCD(1, 515) = ( 1 x 515 ) / 515

= 1 / 515

= 1

Step3:

LCM(1, 164) = 164

GCD(1, 164) = ( 1 x 164 ) / 164

= 1 / 164

= 1

So, Greatest Common Divisor of 257, 100, 515, 164 is 1
