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 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 459 are 3 x 3 x 3 x 17

Prime factors of 746 are 2 x 373

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

Given numbers are 640, 828, 459, 746

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

Apply this formula for all numbers.

Step1:

LCM(640, 828) = 132480

GCD(640, 828) = ( 640 x 828 ) / 132480

= 640 / 828

= 640

Step2:

LCM(4, 459) = 1836

GCD(4, 459) = ( 4 x 459 ) / 1836

= 4 / 459

= 4

Step3:

LCM(1, 746) = 746

GCD(1, 746) = ( 1 x 746 ) / 746

= 1 / 746

= 1

So, Greatest Common Divisor of 640, 828, 459, 746 is 1
