Given numbers are 640, 301, 495, 259

The list of prime factors of all numbers are

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 301 are 7 x 43

Prime factors of 495 are 3 x 3 x 5 x 11

Prime factors of 259 are 7 x 37

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

Given numbers are 640, 301, 495, 259

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

Apply this formula for all numbers.

Step1:

LCM(640, 301) = 192640

GCD(640, 301) = ( 640 x 301 ) / 192640

= 640 / 301

= 640

Step2:

LCM(1, 495) = 495

GCD(1, 495) = ( 1 x 495 ) / 495

= 1 / 495

= 1

Step3:

LCM(1, 259) = 259

GCD(1, 259) = ( 1 x 259 ) / 259

= 1 / 259

= 1

So, Greatest Common Divisor of 640, 301, 495, 259 is 1
