Given numbers are 431, 420, 441, 309

The list of prime factors of all numbers are

Prime factors of 431 are 431

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 309 are 3 x 103

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

Given numbers are 431, 420, 441, 309

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

Apply this formula for all numbers.

Step1:

LCM(431, 420) = 181020

GCD(431, 420) = ( 431 x 420 ) / 181020

= 431 / 420

= 431

Step2:

LCM(1, 441) = 441

GCD(1, 441) = ( 1 x 441 ) / 441

= 1 / 441

= 1

Step3:

LCM(1, 309) = 309

GCD(1, 309) = ( 1 x 309 ) / 309

= 1 / 309

= 1

So, Greatest Common Divisor of 431, 420, 441, 309 is 1
