Given numbers are 408, 129, 228, 220

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 129 are 3 x 43

Prime factors of 228 are 2 x 2 x 3 x 19

Prime factors of 220 are 2 x 2 x 5 x 11

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

Given numbers are 408, 129, 228, 220

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

Apply this formula for all numbers.

Step1:

LCM(408, 129) = 17544

GCD(408, 129) = ( 408 x 129 ) / 17544

= 408 / 129

= 408

Step2:

LCM(3, 228) = 228

GCD(3, 228) = ( 3 x 228 ) / 228

= 3 / 228

= 3

Step3:

LCM(3, 220) = 660

GCD(3, 220) = ( 3 x 220 ) / 660

= 3 / 220

= 3

So, Greatest Common Divisor of 408, 129, 228, 220 is 1
