Given Input Data is 290, 220, 430

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

Prime Factorization of 290 is 2 x 5 x 29

Prime Factorization of 220 is 2 x 2 x 5 x 11

Prime Factorization of 430 is 2 x 5 x 43

Highest common occurrences in the given inputs are 2¹ x 5¹

Multiplying them we get the GCD as 10

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(290, 220) = 6380

GCD(290, 220) = ( 290 x 220 ) / 6380

GCD(290, 220) = 63800 / 6380

GCD(290, 220) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 430

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

LCM(10, 430) = 430

GCD(10, 430) = ( 10 x 430 ) / 430

GCD(10, 430) = 4300 / 430

GCD(10, 430) = 10

GCD of 290, 220, 430 is 10
