Given numbers are 405, 755, 223, 580

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

Apply this formula for all numbers.

Step1:

LCM(405, 755) = 61155

GCD(405, 755) = ( 405 x 755 ) / 61155

= 405 / 755

= 405

Step2:

LCM(5, 223) = 1115

GCD(5, 223) = ( 5 x 223 ) / 1115

= 5 / 223

= 5

Step3:

LCM(1, 580) = 580

GCD(1, 580) = ( 1 x 580 ) / 580

= 1 / 580

= 1

So, Greatest Common Divisor of 405, 755, 223, 580 is 1
