Given numbers are 500, 578, 784, 643

The list of prime factors of all numbers are

Prime factors of 500 are 2 x 2 x 5 x 5 x 5

Prime factors of 578 are 2 x 17 x 17

Prime factors of 784 are 2 x 2 x 2 x 2 x 7 x 7

Prime factors of 643 are 643

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

Given numbers are 500, 578, 784, 643

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

Apply this formula for all numbers.

Step1:

LCM(500, 578) = 144500

GCD(500, 578) = ( 500 x 578 ) / 144500

= 500 / 578

= 500

Step2:

LCM(2, 784) = 784

GCD(2, 784) = ( 2 x 784 ) / 784

= 2 / 784

= 2

Step3:

LCM(2, 643) = 1286

GCD(2, 643) = ( 2 x 643 ) / 1286

= 2 / 643

= 2

So, Greatest Common Divisor of 500, 578, 784, 643 is 1
