Given numbers are 168, 471, 781, 324

The list of prime factors of all numbers are

Prime factors of 168 are 2 x 2 x 2 x 3 x 7

Prime factors of 471 are 3 x 157

Prime factors of 781 are 11 x 71

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 168, 471, 781, 324

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

Apply this formula for all numbers.

Step1:

LCM(168, 471) = 26376

GCD(168, 471) = ( 168 x 471 ) / 26376

= 168 / 471

= 168

Step2:

LCM(3, 781) = 2343

GCD(3, 781) = ( 3 x 781 ) / 2343

= 3 / 781

= 3

Step3:

LCM(1, 324) = 324

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

= 1 / 324

= 1

So, Greatest Common Divisor of 168, 471, 781, 324 is 1
