Given numbers are 390, 220, 429, 228

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

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

Prime factors of 429 are 3 x 11 x 13

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

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

Given numbers are 390, 220, 429, 228

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

Apply this formula for all numbers.

Step1:

LCM(390, 220) = 8580

GCD(390, 220) = ( 390 x 220 ) / 8580

= 390 / 220

= 390

Step2:

LCM(10, 429) = 4290

GCD(10, 429) = ( 10 x 429 ) / 4290

= 10 / 429

= 10

Step3:

LCM(1, 228) = 228

GCD(1, 228) = ( 1 x 228 ) / 228

= 1 / 228

= 1

So, Greatest Common Divisor of 390, 220, 429, 228 is 1
