Given numbers are 640, 470, 187, 324

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 470 are 2 x 5 x 47

Prime factors of 187 are 11 x 17

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 640, 470, 187, 324

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

Apply this formula for all numbers.

Step1:

LCM(640, 470) = 30080

GCD(640, 470) = ( 640 x 470 ) / 30080

= 640 / 470

= 640

Step2:

LCM(10, 187) = 1870

GCD(10, 187) = ( 10 x 187 ) / 1870

= 10 / 187

= 10

Step3:

LCM(1, 324) = 324

GCD(1, 324) = ( 1 x 324 ) / 324

= 1 / 324

= 1

So, Greatest Common Divisor of 640, 470, 187, 324 is 1
