Given numbers are 963, 786, 798, 645

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

Apply this formula for all numbers.

Step1:

LCM(963, 786) = 252306

GCD(963, 786) = ( 963 x 786 ) / 252306

= 963 / 786

= 963

Step2:

LCM(3, 798) = 798

GCD(3, 798) = ( 3 x 798 ) / 798

= 3 / 798

= 3

Step3:

LCM(3, 645) = 645

GCD(3, 645) = ( 3 x 645 ) / 645

= 3 / 645

= 3

So, Greatest Common Divisor of 963, 786, 798, 645 is 3
