Given numbers are 685, 437, 837, 447

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

Apply this formula for all numbers.

Step1:

LCM(685, 437) = 299345

GCD(685, 437) = ( 685 x 437 ) / 299345

= 685 / 437

= 685

Step2:

LCM(1, 837) = 837

GCD(1, 837) = ( 1 x 837 ) / 837

= 1 / 837

= 1

Step3:

LCM(1, 447) = 447

GCD(1, 447) = ( 1 x 447 ) / 447

= 1 / 447

= 1

So, Greatest Common Divisor of 685, 437, 837, 447 is 1
