Given numbers are 325, 520, 34, 257

The list of prime factors of all numbers are

Prime factors of 325 are 5 x 5 x 13

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 34 are 2 x 17

Prime factors of 257 are 257

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

Given numbers are 325, 520, 34, 257

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

Apply this formula for all numbers.

Step1:

LCM(325, 520) = 2600

GCD(325, 520) = ( 325 x 520 ) / 2600

= 325 / 520

= 325

Step2:

LCM(65, 34) = 2210

GCD(65, 34) = ( 65 x 34 ) / 2210

= 65 / 34

= 65

Step3:

LCM(1, 257) = 257

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

= 1 / 257

= 1

So, Greatest Common Divisor of 325, 520, 34, 257 is 1
