Given numbers are 638, 852, 447, 772

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 852 are 2 x 2 x 3 x 71

Prime factors of 447 are 3 x 149

Prime factors of 772 are 2 x 2 x 193

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

Given numbers are 638, 852, 447, 772

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

Apply this formula for all numbers.

Step1:

LCM(638, 852) = 271788

GCD(638, 852) = ( 638 x 852 ) / 271788

= 638 / 852

= 638

Step2:

LCM(2, 447) = 894

GCD(2, 447) = ( 2 x 447 ) / 894

= 2 / 447

= 2

Step3:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

So, Greatest Common Divisor of 638, 852, 447, 772 is 1
