Given numbers are 638, 864, 473, 428

The list of prime factors of all numbers are

Prime factors of 638 are 2 x 11 x 29

Prime factors of 864 are 2 x 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 473 are 11 x 43

Prime factors of 428 are 2 x 2 x 107

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

Given numbers are 638, 864, 473, 428

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

Apply this formula for all numbers.

Step1:

LCM(638, 864) = 275616

GCD(638, 864) = ( 638 x 864 ) / 275616

= 638 / 864

= 638

Step2:

LCM(2, 473) = 946

GCD(2, 473) = ( 2 x 473 ) / 946

= 2 / 473

= 2

Step3:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

So, Greatest Common Divisor of 638, 864, 473, 428 is 1
