Given numbers are 378, 380, 558, 391

The list of prime factors of all numbers are

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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

Prime factors of 558 are 2 x 3 x 3 x 31

Prime factors of 391 are 17 x 23

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

Given numbers are 378, 380, 558, 391

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

Apply this formula for all numbers.

Step1:

LCM(378, 380) = 71820

GCD(378, 380) = ( 378 x 380 ) / 71820

= 378 / 380

= 378

Step2:

LCM(2, 558) = 558

GCD(2, 558) = ( 2 x 558 ) / 558

= 2 / 558

= 2

Step3:

LCM(2, 391) = 782

GCD(2, 391) = ( 2 x 391 ) / 782

= 2 / 391

= 2

So, Greatest Common Divisor of 378, 380, 558, 391 is 1
