Given numbers are 393, 154, 428, 324

The list of prime factors of all numbers are

Prime factors of 393 are 3 x 131

Prime factors of 154 are 2 x 7 x 11

Prime factors of 428 are 2 x 2 x 107

Prime factors of 324 are 2 x 2 x 3 x 3 x 3 x 3

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

Given numbers are 393, 154, 428, 324

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

Apply this formula for all numbers.

Step1:

LCM(393, 154) = 60522

GCD(393, 154) = ( 393 x 154 ) / 60522

= 393 / 154

= 393

Step2:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

Step3:

LCM(1, 324) = 324

GCD(1, 324) = ( 1 x 324 ) / 324

= 1 / 324

= 1

So, Greatest Common Divisor of 393, 154, 428, 324 is 1
