Given numbers are 922, 399, 408, 638

The list of prime factors of all numbers are

Prime factors of 922 are 2 x 461

Prime factors of 399 are 3 x 7 x 19

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 922, 399, 408, 638

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

Apply this formula for all numbers.

Step1:

LCM(922, 399) = 367878

GCD(922, 399) = ( 922 x 399 ) / 367878

= 922 / 399

= 922

Step2:

LCM(1, 408) = 408

GCD(1, 408) = ( 1 x 408 ) / 408

= 1 / 408

= 1

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 922, 399, 408, 638 is 1
