Given numbers are 405, 581, 436, 290

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

Apply this formula for all numbers.

Step1:

LCM(405, 581) = 235305

GCD(405, 581) = ( 405 x 581 ) / 235305

= 405 / 581

= 405

Step2:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

Step3:

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

= 1 / 290

= 1

So, Greatest Common Divisor of 405, 581, 436, 290 is 1
