Given numbers are 438, 638, 205, 546

The list of prime factors of all numbers are

Prime factors of 438 are 2 x 3 x 73

Prime factors of 638 are 2 x 11 x 29

Prime factors of 205 are 5 x 41

Prime factors of 546 are 2 x 3 x 7 x 13

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

Given numbers are 438, 638, 205, 546

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

Apply this formula for all numbers.

Step1:

LCM(438, 638) = 139722

GCD(438, 638) = ( 438 x 638 ) / 139722

= 438 / 638

= 438

Step2:

LCM(2, 205) = 410

GCD(2, 205) = ( 2 x 205 ) / 410

= 2 / 205

= 2

Step3:

LCM(1, 546) = 546

GCD(1, 546) = ( 1 x 546 ) / 546

= 1 / 546

= 1

So, Greatest Common Divisor of 438, 638, 205, 546 is 1
