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

Apply this formula for all numbers.

Step1:

LCM(234, 783) = 20358

GCD(234, 783) = ( 234 x 783 ) / 20358

= 234 / 783

= 234

Step2:

LCM(9, 663) = 1989

GCD(9, 663) = ( 9 x 663 ) / 1989

= 9 / 663

= 9

Step3:

LCM(3, 861) = 861

GCD(3, 861) = ( 3 x 861 ) / 861

= 3 / 861

= 3

So, Greatest Common Divisor of 234, 783, 663, 861 is 3
