Given numbers are 409, 447, 905, 506

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

Apply this formula for all numbers.

Step1:

LCM(409, 447) = 182823

GCD(409, 447) = ( 409 x 447 ) / 182823

= 409 / 447

= 409

Step2:

LCM(1, 905) = 905

GCD(1, 905) = ( 1 x 905 ) / 905

= 1 / 905

= 1

Step3:

LCM(1, 506) = 506

GCD(1, 506) = ( 1 x 506 ) / 506

= 1 / 506

= 1

So, Greatest Common Divisor of 409, 447, 905, 506 is 1
