Given numbers are 731, 315, 142, 439

The list of prime factors of all numbers are

Prime factors of 731 are 17 x 43

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 142 are 2 x 71

Prime factors of 439 are 439

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

Given numbers are 731, 315, 142, 439

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

Apply this formula for all numbers.

Step1:

LCM(731, 315) = 230265

GCD(731, 315) = ( 731 x 315 ) / 230265

= 731 / 315

= 731

Step2:

LCM(1, 142) = 142

GCD(1, 142) = ( 1 x 142 ) / 142

= 1 / 142

= 1

Step3:

LCM(1, 439) = 439

GCD(1, 439) = ( 1 x 439 ) / 439

= 1 / 439

= 1

So, Greatest Common Divisor of 731, 315, 142, 439 is 1
