Given numbers are 381, 329, 390, 320

The list of prime factors of all numbers are

Prime factors of 381 are 3 x 127

Prime factors of 329 are 7 x 47

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

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 381, 329, 390, 320

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

Apply this formula for all numbers.

Step1:

LCM(381, 329) = 125349

GCD(381, 329) = ( 381 x 329 ) / 125349

= 381 / 329

= 381

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 320) = 320

GCD(1, 320) = ( 1 x 320 ) / 320

= 1 / 320

= 1

So, Greatest Common Divisor of 381, 329, 390, 320 is 1
