Given numbers are 561, 906, 417, 444

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

Apply this formula for all numbers.

Step1:

LCM(561, 906) = 169422

GCD(561, 906) = ( 561 x 906 ) / 169422

= 561 / 906

= 561

Step2:

LCM(3, 417) = 417

GCD(3, 417) = ( 3 x 417 ) / 417

= 3 / 417

= 3

Step3:

LCM(3, 444) = 444

GCD(3, 444) = ( 3 x 444 ) / 444

= 3 / 444

= 3

So, Greatest Common Divisor of 561, 906, 417, 444 is 3
