Given Input Data is 620, 240, 688

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 240 is 2 x 2 x 2 x 2 x 3 x 5

Prime Factorization of 688 is 2 x 2 x 2 x 2 x 43

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, 240) = 7440

GCD(620, 240) = ( 620 x 240 ) / 7440

GCD(620, 240) = 148800 / 7440

GCD(620, 240) = 20

Step2:

Here we consider the GCD from the above i.e. 20 as first number and the next as 688

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

LCM(20, 688) = 3440

GCD(20, 688) = ( 20 x 688 ) / 3440

GCD(20, 688) = 13760 / 3440

GCD(20, 688) = 4

GCD of 620, 240, 688 is 4
