Given numbers are 393, 340, 990, 108

The list of prime factors of all numbers are

Prime factors of 393 are 3 x 131

Prime factors of 340 are 2 x 2 x 5 x 17

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 108 are 2 x 2 x 3 x 3 x 3

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

Given numbers are 393, 340, 990, 108

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

Apply this formula for all numbers.

Step1:

LCM(393, 340) = 133620

GCD(393, 340) = ( 393 x 340 ) / 133620

= 393 / 340

= 393

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 108) = 108

GCD(1, 108) = ( 1 x 108 ) / 108

= 1 / 108

= 1

So, Greatest Common Divisor of 393, 340, 990, 108 is 1
