Given numbers are 405, 872, 410, 665

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

Apply this formula for all numbers.

Step1:

LCM(405, 872) = 353160

GCD(405, 872) = ( 405 x 872 ) / 353160

= 405 / 872

= 405

Step2:

LCM(1, 410) = 410

GCD(1, 410) = ( 1 x 410 ) / 410

= 1 / 410

= 1

Step3:

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

= 1 / 665

= 1

So, Greatest Common Divisor of 405, 872, 410, 665 is 1
