Given numbers are 259, 560, 640, 458

The list of prime factors of all numbers are

Prime factors of 259 are 7 x 37

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

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

Prime factors of 458 are 2 x 229

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

Given numbers are 259, 560, 640, 458

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

Apply this formula for all numbers.

Step1:

LCM(259, 560) = 20720

GCD(259, 560) = ( 259 x 560 ) / 20720

= 259 / 560

= 259

Step2:

LCM(7, 640) = 4480

GCD(7, 640) = ( 7 x 640 ) / 4480

= 7 / 640

= 7

Step3:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

So, Greatest Common Divisor of 259, 560, 640, 458 is 1
