Given numbers are 408, 346, 265, 638

The list of prime factors of all numbers are

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

Prime factors of 346 are 2 x 173

Prime factors of 265 are 5 x 53

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 408, 346, 265, 638

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

Apply this formula for all numbers.

Step1:

LCM(408, 346) = 70584

GCD(408, 346) = ( 408 x 346 ) / 70584

= 408 / 346

= 408

Step2:

LCM(2, 265) = 530

GCD(2, 265) = ( 2 x 265 ) / 530

= 2 / 265

= 2

Step3:

LCM(1, 638) = 638

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

= 1 / 638

= 1

So, Greatest Common Divisor of 408, 346, 265, 638 is 1
