Given numbers are 556, 429, 561

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

Apply this formula for all numbers.

Step1:

LCM(556, 429) = 238524

GCD(556, 429) = ( 556 x 429 ) / 238524

= 556 / 429

= 556

Step2:

LCM(1, 561) = 561

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

= 1 / 561

= 1

So, Greatest Common Divisor of 556, 429, 561 is 1
