Given numbers are 124, 127, 561

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

Apply this formula for all numbers.

Step1:

LCM(124, 127) = 15748

GCD(124, 127) = ( 124 x 127 ) / 15748

= 124 / 127

= 124

Step2:

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

= 1 / 561

= 1

So, Greatest Common Divisor of 124, 127, 561 is 1
