Given Input Data is 356, 216, 620

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

Prime Factorization of 356 is 2 x 2 x 89

Prime Factorization of 216 is 2 x 2 x 2 x 3 x 3 x 3

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

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(356, 216) = 19224

GCD(356, 216) = ( 356 x 216 ) / 19224

GCD(356, 216) = 76896 / 19224

GCD(356, 216) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 620

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

LCM(4, 620) = 620

GCD(4, 620) = ( 4 x 620 ) / 620

GCD(4, 620) = 2480 / 620

GCD(4, 620) = 4

GCD of 356, 216, 620 is 4
