Given numbers are 405, 146, 688, 285

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

Apply this formula for all numbers.

Step1:

LCM(405, 146) = 59130

GCD(405, 146) = ( 405 x 146 ) / 59130

= 405 / 146

= 405

Step2:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

Step3:

LCM(1, 285) = 285

GCD(1, 285) = ( 1 x 285 ) / 285

= 1 / 285

= 1

So, Greatest Common Divisor of 405, 146, 688, 285 is 1
