The list of prime factors of all numbers are

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

Prime factors of 142 are 2 x 71

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 669 are 3 x 223

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

Given numbers are 392, 142, 360, 669

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

Apply this formula for all numbers.

Step1:

LCM(392, 142) = 27832

GCD(392, 142) = ( 392 x 142 ) / 27832

= 392 / 142

= 392

Step2:

LCM(2, 360) = 360

GCD(2, 360) = ( 2 x 360 ) / 360

= 2 / 360

= 2

Step3:

LCM(2, 669) = 1338

GCD(2, 669) = ( 2 x 669 ) / 1338

= 2 / 669

= 2

So, Greatest Common Divisor of 392, 142, 360, 669 is 1
