Given Input Data is 820, 784, 700

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

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

Prime Factorization of 784 is 2 x 2 x 2 x 2 x 7 x 7

Prime Factorization of 700 is 2 x 2 x 5 x 5 x 7

Highest common occurrences in the given inputs are 2²

Multiplying them we get the GCD as 4

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(820, 784) = 160720

GCD(820, 784) = ( 820 x 784 ) / 160720

GCD(820, 784) = 642880 / 160720

GCD(820, 784) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 700

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

LCM(4, 700) = 700

GCD(4, 700) = ( 4 x 700 ) / 700

GCD(4, 700) = 2800 / 700

GCD(4, 700) = 4

GCD of 820, 784, 700 is 4
