Given numbers are 640, 420, 576, 807

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 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 576 are 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime factors of 807 are 3 x 269

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

Given numbers are 640, 420, 576, 807

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

Apply this formula for all numbers.

Step1:

LCM(640, 420) = 13440

GCD(640, 420) = ( 640 x 420 ) / 13440

= 640 / 420

= 640

Step2:

LCM(20, 576) = 2880

GCD(20, 576) = ( 20 x 576 ) / 2880

= 20 / 576

= 20

Step3:

LCM(4, 807) = 3228

GCD(4, 807) = ( 4 x 807 ) / 3228

= 4 / 807

= 4

So, Greatest Common Divisor of 640, 420, 576, 807 is 1
