Given numbers are 319, 847, 409, 405

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

Apply this formula for all numbers.

Step1:

LCM(319, 847) = 24563

GCD(319, 847) = ( 319 x 847 ) / 24563

= 319 / 847

= 319

Step2:

LCM(11, 409) = 4499

GCD(11, 409) = ( 11 x 409 ) / 4499

= 11 / 409

= 11

Step3:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

So, Greatest Common Divisor of 319, 847, 409, 405 is 1
