Given numbers are 561, 639, 335

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

Apply this formula for all numbers.

Step1:

LCM(561, 639) = 119493

GCD(561, 639) = ( 561 x 639 ) / 119493

= 561 / 639

= 561

Step2:

LCM(3, 335) = 1005

GCD(3, 335) = ( 3 x 335 ) / 1005

= 3 / 335

= 3

So, Greatest Common Divisor of 561, 639, 335 is 1
