Given numbers are 203, 407, 685, 324

The list of prime factors of all numbers are

Prime factors of 203 are 7 x 29

Prime factors of 407 are 11 x 37

Prime factors of 685 are 5 x 137

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 203, 407, 685, 324

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

Apply this formula for all numbers.

Step1:

LCM(203, 407) = 82621

GCD(203, 407) = ( 203 x 407 ) / 82621

= 203 / 407

= 203

Step2:

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

= 1 / 685

= 1

Step3:

LCM(1, 324) = 324

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

= 1 / 324

= 1

So, Greatest Common Divisor of 203, 407, 685, 324 is 1
