Given numbers are 423, 984, 520, 393

The list of prime factors of all numbers are

Prime factors of 423 are 3 x 3 x 47

Prime factors of 984 are 2 x 2 x 2 x 3 x 41

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 393 are 3 x 131

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

Given numbers are 423, 984, 520, 393

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

Apply this formula for all numbers.

Step1:

LCM(423, 984) = 138744

GCD(423, 984) = ( 423 x 984 ) / 138744

= 423 / 984

= 423

Step2:

LCM(3, 520) = 1560

GCD(3, 520) = ( 3 x 520 ) / 1560

= 3 / 520

= 3

Step3:

LCM(1, 393) = 393

GCD(1, 393) = ( 1 x 393 ) / 393

= 1 / 393

= 1

So, Greatest Common Divisor of 423, 984, 520, 393 is 1
