Given numbers are 561, 680, 823, 519

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

Apply this formula for all numbers.

Step1:

LCM(561, 680) = 22440

GCD(561, 680) = ( 561 x 680 ) / 22440

= 561 / 680

= 561

Step2:

LCM(17, 823) = 13991

GCD(17, 823) = ( 17 x 823 ) / 13991

= 17 / 823

= 17

Step3:

LCM(1, 519) = 519

GCD(1, 519) = ( 1 x 519 ) / 519

= 1 / 519

= 1

So, Greatest Common Divisor of 561, 680, 823, 519 is 1
