Given numbers are 640, 522, 219, 100

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 522 are 2 x 3 x 3 x 29

Prime factors of 219 are 3 x 73

Prime factors of 100 are 2 x 2 x 5 x 5

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

Given numbers are 640, 522, 219, 100

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

Apply this formula for all numbers.

Step1:

LCM(640, 522) = 167040

GCD(640, 522) = ( 640 x 522 ) / 167040

= 640 / 522

= 640

Step2:

LCM(2, 219) = 438

GCD(2, 219) = ( 2 x 219 ) / 438

= 2 / 219

= 2

Step3:

LCM(1, 100) = 100

GCD(1, 100) = ( 1 x 100 ) / 100

= 1 / 100

= 1

So, Greatest Common Divisor of 640, 522, 219, 100 is 1
