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

Apply this formula for all numbers.

Step1:

LCM(561, 642) = 120054

GCD(561, 642) = ( 561 x 642 ) / 120054

= 561 / 642

= 561

Step2:

LCM(3, 114) = 114

GCD(3, 114) = ( 3 x 114 ) / 114

= 3 / 114

= 3

So, Greatest Common Divisor of 561, 642, 114 is 3
