Given numbers are 405, 355, 659, 487

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

Apply this formula for all numbers.

Step1:

LCM(405, 355) = 28755

GCD(405, 355) = ( 405 x 355 ) / 28755

= 405 / 355

= 405

Step2:

LCM(5, 659) = 3295

GCD(5, 659) = ( 5 x 659 ) / 3295

= 5 / 659

= 5

Step3:

LCM(1, 487) = 487

GCD(1, 487) = ( 1 x 487 ) / 487

= 1 / 487

= 1

So, Greatest Common Divisor of 405, 355, 659, 487 is 1
