Given numbers are 390, 478, 143, 570

The list of prime factors of all numbers are

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

Prime factors of 478 are 2 x 239

Prime factors of 143 are 11 x 13

Prime factors of 570 are 2 x 3 x 5 x 19

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

Given numbers are 390, 478, 143, 570

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

Apply this formula for all numbers.

Step1:

LCM(390, 478) = 93210

GCD(390, 478) = ( 390 x 478 ) / 93210

= 390 / 478

= 390

Step2:

LCM(2, 143) = 286

GCD(2, 143) = ( 2 x 143 ) / 286

= 2 / 143

= 2

Step3:

LCM(1, 570) = 570

GCD(1, 570) = ( 1 x 570 ) / 570

= 1 / 570

= 1

So, Greatest Common Divisor of 390, 478, 143, 570 is 1
