Given numbers are 393, 738, 255, 940

The list of prime factors of all numbers are

Prime factors of 393 are 3 x 131

Prime factors of 738 are 2 x 3 x 3 x 41

Prime factors of 255 are 3 x 5 x 17

Prime factors of 940 are 2 x 2 x 5 x 47

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

Given numbers are 393, 738, 255, 940

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

Apply this formula for all numbers.

Step1:

LCM(393, 738) = 96678

GCD(393, 738) = ( 393 x 738 ) / 96678

= 393 / 738

= 393

Step2:

LCM(3, 255) = 255

GCD(3, 255) = ( 3 x 255 ) / 255

= 3 / 255

= 3

Step3:

LCM(3, 940) = 2820

GCD(3, 940) = ( 3 x 940 ) / 2820

= 3 / 940

= 3

So, Greatest Common Divisor of 393, 738, 255, 940 is 1
