Given numbers are 285, 434, 431, 744

The list of prime factors of all numbers are

Prime factors of 285 are 3 x 5 x 19

Prime factors of 434 are 2 x 7 x 31

Prime factors of 431 are 431

Prime factors of 744 are 2 x 2 x 2 x 3 x 31

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

Given numbers are 285, 434, 431, 744

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

Apply this formula for all numbers.

Step1:

LCM(285, 434) = 123690

GCD(285, 434) = ( 285 x 434 ) / 123690

= 285 / 434

= 285

Step2:

LCM(1, 431) = 431

GCD(1, 431) = ( 1 x 431 ) / 431

= 1 / 431

= 1

Step3:

LCM(1, 744) = 744

GCD(1, 744) = ( 1 x 744 ) / 744

= 1 / 744

= 1

So, Greatest Common Divisor of 285, 434, 431, 744 is 1
