Given numbers are 640, 672, 404, 810

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

Apply this formula for all numbers.

Step1:

LCM(640, 672) = 13440

GCD(640, 672) = ( 640 x 672 ) / 13440

= 640 / 672

= 640

Step2:

LCM(32, 404) = 3232

GCD(32, 404) = ( 32 x 404 ) / 3232

= 32 / 404

= 32

Step3:

LCM(4, 810) = 1620

GCD(4, 810) = ( 4 x 810 ) / 1620

= 4 / 810

= 4

So, Greatest Common Divisor of 640, 672, 404, 810 is 2
