Given numbers are 561, 816, 11, 833

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

Apply this formula for all numbers.

Step1:

LCM(561, 816) = 8976

GCD(561, 816) = ( 561 x 816 ) / 8976

= 561 / 816

= 561

Step2:

LCM(51, 11) = 561

GCD(51, 11) = ( 51 x 11 ) / 561

= 51 / 11

= 51

Step3:

LCM(1, 833) = 833

GCD(1, 833) = ( 1 x 833 ) / 833

= 1 / 833

= 1

So, Greatest Common Divisor of 561, 816, 11, 833 is 1
