Given numbers are 405, 188, 248, 805

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

Apply this formula for all numbers.

Step1:

LCM(405, 188) = 76140

GCD(405, 188) = ( 405 x 188 ) / 76140

= 405 / 188

= 405

Step2:

LCM(1, 248) = 248

GCD(1, 248) = ( 1 x 248 ) / 248

= 1 / 248

= 1

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 405, 188, 248, 805 is 1
