Given numbers are 561, 563, 903

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

Apply this formula for all numbers.

Step1:

LCM(561, 563) = 315843

GCD(561, 563) = ( 561 x 563 ) / 315843

= 561 / 563

= 561

Step2:

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

= 1 / 903

= 1

So, Greatest Common Divisor of 561, 563, 903 is 1
