Given numbers are 945, 789, 717, 865

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

Apply this formula for all numbers.

Step1:

LCM(945, 789) = 248535

GCD(945, 789) = ( 945 x 789 ) / 248535

= 945 / 789

= 945

Step2:

LCM(3, 717) = 717

GCD(3, 717) = ( 3 x 717 ) / 717

= 3 / 717

= 3

Step3:

LCM(3, 865) = 2595

GCD(3, 865) = ( 3 x 865 ) / 2595

= 3 / 865

= 3

So, Greatest Common Divisor of 945, 789, 717, 865 is 1
