Given numbers are 392, 391, 437, 817

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

Apply this formula for all numbers.

Step1:

LCM(392, 391) = 153272

GCD(392, 391) = ( 392 x 391 ) / 153272

= 392 / 391

= 392

Step2:

LCM(1, 437) = 437

GCD(1, 437) = ( 1 x 437 ) / 437

= 1 / 437

= 1

Step3:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

So, Greatest Common Divisor of 392, 391, 437, 817 is 1
