Given numbers are 840, 706, 437, 439

The list of prime factors of all numbers are

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 706 are 2 x 353

Prime factors of 437 are 19 x 23

Prime factors of 439 are 439

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

Given numbers are 840, 706, 437, 439

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

Apply this formula for all numbers.

Step1:

LCM(840, 706) = 296520

GCD(840, 706) = ( 840 x 706 ) / 296520

= 840 / 706

= 840

Step2:

LCM(2, 437) = 874

GCD(2, 437) = ( 2 x 437 ) / 874

= 2 / 437

= 2

Step3:

LCM(1, 439) = 439

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

= 1 / 439

= 1

So, Greatest Common Divisor of 840, 706, 437, 439 is 1
