Given numbers are 561, 436, 817

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

Apply this formula for all numbers.

Step1:

LCM(561, 436) = 244596

GCD(561, 436) = ( 561 x 436 ) / 244596

= 561 / 436

= 561

Step2:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

So, Greatest Common Divisor of 561, 436, 817 is 1
