Given numbers are 561, 218, 885, 417

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

Apply this formula for all numbers.

Step1:

LCM(561, 218) = 122298

GCD(561, 218) = ( 561 x 218 ) / 122298

= 561 / 218

= 561

Step2:

LCM(1, 885) = 885

GCD(1, 885) = ( 1 x 885 ) / 885

= 1 / 885

= 1

Step3:

LCM(1, 417) = 417

GCD(1, 417) = ( 1 x 417 ) / 417

= 1 / 417

= 1

So, Greatest Common Divisor of 561, 218, 885, 417 is 1
