Given numbers are 247, 295, 405, 418

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

Apply this formula for all numbers.

Step1:

LCM(247, 295) = 72865

GCD(247, 295) = ( 247 x 295 ) / 72865

= 247 / 295

= 247

Step2:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

Step3:

LCM(1, 418) = 418

GCD(1, 418) = ( 1 x 418 ) / 418

= 1 / 418

= 1

So, Greatest Common Divisor of 247, 295, 405, 418 is 1
