Given numbers are 945, 420, 768, 717

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

Apply this formula for all numbers.

Step1:

LCM(945, 420) = 3780

GCD(945, 420) = ( 945 x 420 ) / 3780

= 945 / 420

= 945

Step2:

LCM(105, 768) = 26880

GCD(105, 768) = ( 105 x 768 ) / 26880

= 105 / 768

= 105

Step3:

LCM(3, 717) = 717

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

= 3 / 717

= 3

So, Greatest Common Divisor of 945, 420, 768, 717 is 3
