Given numbers are 378, 481, 105, 287

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 481 are 13 x 37

Prime factors of 105 are 3 x 5 x 7

Prime factors of 287 are 7 x 41

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

Given numbers are 378, 481, 105, 287

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

Apply this formula for all numbers.

Step1:

LCM(378, 481) = 181818

GCD(378, 481) = ( 378 x 481 ) / 181818

= 378 / 481

= 378

Step2:

LCM(1, 105) = 105

GCD(1, 105) = ( 1 x 105 ) / 105

= 1 / 105

= 1

Step3:

LCM(1, 287) = 287

GCD(1, 287) = ( 1 x 287 ) / 287

= 1 / 287

= 1

So, Greatest Common Divisor of 378, 481, 105, 287 is 1
