Given numbers are 205, 120, 478, 406

The list of prime factors of all numbers are

Prime factors of 205 are 5 x 41

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 478 are 2 x 239

Prime factors of 406 are 2 x 7 x 29

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

Given numbers are 205, 120, 478, 406

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

Apply this formula for all numbers.

Step1:

LCM(205, 120) = 4920

GCD(205, 120) = ( 205 x 120 ) / 4920

= 205 / 120

= 205

Step2:

LCM(5, 478) = 2390

GCD(5, 478) = ( 5 x 478 ) / 2390

= 5 / 478

= 5

Step3:

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

= 1 / 406

= 1

So, Greatest Common Divisor of 205, 120, 478, 406 is 1
