Given Input Data is 315, 315, 80, 620

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

Prime Factorization of 315 is 3 x 3 x 5 x 7

Prime Factorization of 315 is 3 x 3 x 5 x 7

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 620 is 2 x 2 x 5 x 31

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(315, 315) = 315

GCD(315, 315) = ( 315 x 315 ) / 315

GCD(315, 315) = 99225 / 315

GCD(315, 315) = 315

Step2:

Here we consider the GCD from the above i.e. 315 as first number and the next as 80

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

LCM(315, 80) = 5040

GCD(315, 80) = ( 315 x 80 ) / 5040

GCD(315, 80) = 25200 / 5040

GCD(315, 80) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 620

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

LCM(5, 620) = 620

GCD(5, 620) = ( 5 x 620 ) / 620

GCD(5, 620) = 3100 / 620

GCD(5, 620) = 5

GCD of 315, 315, 80, 620 is 5
