Given numbers are 578, 480, 457, 394

The list of prime factors of all numbers are

Prime factors of 578 are 2 x 17 x 17

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 457 are 457

Prime factors of 394 are 2 x 197

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

Given numbers are 578, 480, 457, 394

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

Apply this formula for all numbers.

Step1:

LCM(578, 480) = 138720

GCD(578, 480) = ( 578 x 480 ) / 138720

= 578 / 480

= 578

Step2:

LCM(2, 457) = 914

GCD(2, 457) = ( 2 x 457 ) / 914

= 2 / 457

= 2

Step3:

LCM(1, 394) = 394

GCD(1, 394) = ( 1 x 394 ) / 394

= 1 / 394

= 1

So, Greatest Common Divisor of 578, 480, 457, 394 is 1
