Given Input Data is 672, 820, 618, 726

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

Prime Factorization of 672 is 2 x 2 x 2 x 2 x 2 x 3 x 7

Prime Factorization of 820 is 2 x 2 x 5 x 41

Prime Factorization of 618 is 2 x 3 x 103

Prime Factorization of 726 is 2 x 3 x 11 x 11

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

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(672, 820) = 137760

GCD(672, 820) = ( 672 x 820 ) / 137760

GCD(672, 820) = 551040 / 137760

GCD(672, 820) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 618

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

LCM(4, 618) = 1236

GCD(4, 618) = ( 4 x 618 ) / 1236

GCD(4, 618) = 2472 / 1236

GCD(4, 618) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 726

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

LCM(2, 726) = 726

GCD(2, 726) = ( 2 x 726 ) / 726

GCD(2, 726) = 1452 / 726

GCD(2, 726) = 2

GCD of 672, 820, 618, 726 is 2
