Given Input Data is 580, 305, 515, 455

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

Prime Factorization of 580 is 2 x 2 x 5 x 29

Prime Factorization of 305 is 5 x 61

Prime Factorization of 515 is 5 x 103

Prime Factorization of 455 is 5 x 7 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(580, 305) = 35380

GCD(580, 305) = ( 580 x 305 ) / 35380

GCD(580, 305) = 176900 / 35380

GCD(580, 305) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 515

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

LCM(5, 515) = 515

GCD(5, 515) = ( 5 x 515 ) / 515

GCD(5, 515) = 2575 / 515

GCD(5, 515) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 455

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

LCM(5, 455) = 455

GCD(5, 455) = ( 5 x 455 ) / 455

GCD(5, 455) = 2275 / 455

GCD(5, 455) = 5

GCD of 580, 305, 515, 455 is 5
