Given numbers are 254, 438, 371, 408

The list of prime factors of all numbers are

Prime factors of 254 are 2 x 127

Prime factors of 438 are 2 x 3 x 73

Prime factors of 371 are 7 x 53

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

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

Given numbers are 254, 438, 371, 408

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

Apply this formula for all numbers.

Step1:

LCM(254, 438) = 55626

GCD(254, 438) = ( 254 x 438 ) / 55626

= 254 / 438

= 254

Step2:

LCM(2, 371) = 742

GCD(2, 371) = ( 2 x 371 ) / 742

= 2 / 371

= 2

Step3:

LCM(1, 408) = 408

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

= 1 / 408

= 1

So, Greatest Common Divisor of 254, 438, 371, 408 is 1
