Given numbers are 399, 249, 437, 386

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

Apply this formula for all numbers.

Step1:

LCM(399, 249) = 33117

GCD(399, 249) = ( 399 x 249 ) / 33117

= 399 / 249

= 399

Step2:

LCM(3, 437) = 1311

GCD(3, 437) = ( 3 x 437 ) / 1311

= 3 / 437

= 3

Step3:

LCM(1, 386) = 386

GCD(1, 386) = ( 1 x 386 ) / 386

= 1 / 386

= 1

So, Greatest Common Divisor of 399, 249, 437, 386 is 1
