Given numbers are 640, 219, 808, 222

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 219 are 3 x 73

Prime factors of 808 are 2 x 2 x 2 x 101

Prime factors of 222 are 2 x 3 x 37

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

Given numbers are 640, 219, 808, 222

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

Apply this formula for all numbers.

Step1:

LCM(640, 219) = 140160

GCD(640, 219) = ( 640 x 219 ) / 140160

= 640 / 219

= 640

Step2:

LCM(1, 808) = 808

GCD(1, 808) = ( 1 x 808 ) / 808

= 1 / 808

= 1

Step3:

LCM(1, 222) = 222

GCD(1, 222) = ( 1 x 222 ) / 222

= 1 / 222

= 1

So, Greatest Common Divisor of 640, 219, 808, 222 is 1
