Given Input Data is 620, 244, 652, 440

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

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

Prime Factorization of 244 is 2 x 2 x 61

Prime Factorization of 652 is 2 x 2 x 163

Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11

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(620, 244) = 37820

GCD(620, 244) = ( 620 x 244 ) / 37820

GCD(620, 244) = 151280 / 37820

GCD(620, 244) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 652

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

LCM(4, 652) = 652

GCD(4, 652) = ( 4 x 652 ) / 652

GCD(4, 652) = 2608 / 652

GCD(4, 652) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 440

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

LCM(4, 440) = 440

GCD(4, 440) = ( 4 x 440 ) / 440

GCD(4, 440) = 1760 / 440

GCD(4, 440) = 4

GCD of 620, 244, 652, 440 is 4
