Therefore, GCD of numbers 756, 738, 945, 306 is 9

Given Input Data is 756, 738, 945, 306

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 756 is 2 x 2 x 3 x 3 x 3 x 7

Prime Factorization of 738 is 2 x 3 x 3 x 41

Prime Factorization of 945 is 3 x 3 x 3 x 5 x 7

Prime Factorization of 306 is 2 x 3 x 3 x 17

Highest common occurrences in the given inputs are 3²

Multiplying them we get the GCD as 9

Step1:

Let's calculate the GCD of first two numbers

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

LCM(756, 738) = 30996

GCD(756, 738) = ( 756 x 738 ) / 30996

GCD(756, 738) = 557928 / 30996

GCD(756, 738) = 18

Step2:

Here we consider the GCD from the above i.e. 18 as first number and the next as 945

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

LCM(18, 945) = 1890

GCD(18, 945) = ( 18 x 945 ) / 1890

GCD(18, 945) = 17010 / 1890

GCD(18, 945) = 9

Step3:

Here we consider the GCD from the above i.e. 9 as first number and the next as 306

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

LCM(9, 306) = 306

GCD(9, 306) = ( 9 x 306 ) / 306

GCD(9, 306) = 2754 / 306

GCD(9, 306) = 9

GCD of 756, 738, 945, 306 is 9
