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

Apply this formula for all numbers.

Step1:

LCM(963, 261) = 27927

GCD(963, 261) = ( 963 x 261 ) / 27927

= 963 / 261

= 963

Step2:

LCM(9, 721) = 6489

GCD(9, 721) = ( 9 x 721 ) / 6489

= 9 / 721

= 9

So, Greatest Common Divisor of 963, 261, 721 is 1
