Given numbers are 394, 360, 231, 642

The list of prime factors of all numbers are

Prime factors of 394 are 2 x 197

Prime factors of 360 are 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 231 are 3 x 7 x 11

Prime factors of 642 are 2 x 3 x 107

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

Given numbers are 394, 360, 231, 642

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

Apply this formula for all numbers.

Step1:

LCM(394, 360) = 70920

GCD(394, 360) = ( 394 x 360 ) / 70920

= 394 / 360

= 394

Step2:

LCM(2, 231) = 462

GCD(2, 231) = ( 2 x 231 ) / 462

= 2 / 231

= 2

Step3:

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

= 1 / 642

= 1

So, Greatest Common Divisor of 394, 360, 231, 642 is 1
