Given Input Data is 445, 140, 520

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

Prime Factorization of 445 is 5 x 89

Prime Factorization of 140 is 2 x 2 x 5 x 7

Prime Factorization of 520 is 2 x 2 x 2 x 5 x 13

Highest common occurrences in the given inputs are 5¹

Multiplying them we get the GCD as 5

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(445, 140) = 12460

GCD(445, 140) = ( 445 x 140 ) / 12460

GCD(445, 140) = 62300 / 12460

GCD(445, 140) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 520

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

LCM(5, 520) = 520

GCD(5, 520) = ( 5 x 520 ) / 520

GCD(5, 520) = 2600 / 520

GCD(5, 520) = 5

GCD of 445, 140, 520 is 5
