Given numbers are 394, 455, 380, 330

The list of prime factors of all numbers are

Prime factors of 394 are 2 x 197

Prime factors of 455 are 5 x 7 x 13

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 330 are 2 x 3 x 5 x 11

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

Given numbers are 394, 455, 380, 330

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

Apply this formula for all numbers.

Step1:

LCM(394, 455) = 179270

GCD(394, 455) = ( 394 x 455 ) / 179270

= 394 / 455

= 394

Step2:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

Step3:

LCM(1, 330) = 330

GCD(1, 330) = ( 1 x 330 ) / 330

= 1 / 330

= 1

So, Greatest Common Divisor of 394, 455, 380, 330 is 1
