Given Input Data is 815, 625, 485, 305

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

Prime Factorization of 815 is 5 x 163

Prime Factorization of 625 is 5 x 5 x 5 x 5

Prime Factorization of 485 is 5 x 97

Prime Factorization of 305 is 5 x 61

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(815, 625) = 101875

GCD(815, 625) = ( 815 x 625 ) / 101875

GCD(815, 625) = 509375 / 101875

GCD(815, 625) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 485

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

LCM(5, 485) = 485

GCD(5, 485) = ( 5 x 485 ) / 485

GCD(5, 485) = 2425 / 485

GCD(5, 485) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 305

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

LCM(5, 305) = 305

GCD(5, 305) = ( 5 x 305 ) / 305

GCD(5, 305) = 1525 / 305

GCD(5, 305) = 5

GCD of 815, 625, 485, 305 is 5
