Given numbers are 640, 360, 322, 805

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 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 322 are 2 x 7 x 23

Prime factors of 805 are 5 x 7 x 23

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

Given numbers are 640, 360, 322, 805

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

Apply this formula for all numbers.

Step1:

LCM(640, 360) = 5760

GCD(640, 360) = ( 640 x 360 ) / 5760

= 640 / 360

= 640

Step2:

LCM(40, 322) = 6440

GCD(40, 322) = ( 40 x 322 ) / 6440

= 40 / 322

= 40

Step3:

LCM(2, 805) = 1610

GCD(2, 805) = ( 2 x 805 ) / 1610

= 2 / 805

= 2

So, Greatest Common Divisor of 640, 360, 322, 805 is 1
