The list of prime factors of all numbers are

Prime factors of 639 are 3 x 3 x 71

Prime factors of 450 are 2 x 3 x 3 x 5 x 5

Prime factors of 472 are 2 x 2 x 2 x 59

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 639, 450, 472, 768

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

Apply this formula for all numbers.

Step1:

LCM(639, 450) = 31950

GCD(639, 450) = ( 639 x 450 ) / 31950

= 639 / 450

= 639

Step2:

LCM(9, 472) = 4248

GCD(9, 472) = ( 9 x 472 ) / 4248

= 9 / 472

= 9

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 639, 450, 472, 768 is 1
