Given numbers are 408, 669, 441, 866

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

Apply this formula for all numbers.

Step1:

LCM(408, 669) = 90984

GCD(408, 669) = ( 408 x 669 ) / 90984

= 408 / 669

= 408

Step2:

LCM(3, 441) = 441

GCD(3, 441) = ( 3 x 441 ) / 441

= 3 / 441

= 3

Step3:

LCM(3, 866) = 2598

GCD(3, 866) = ( 3 x 866 ) / 2598

= 3 / 866

= 3

So, Greatest Common Divisor of 408, 669, 441, 866 is 1
