Given Input Data is 470, 154, 858

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

Prime Factorization of 470 is 2 x 5 x 47

Prime Factorization of 154 is 2 x 7 x 11

Prime Factorization of 858 is 2 x 3 x 11 x 13

Highest common occurrences in the given inputs are 2¹

Multiplying them we get the GCD as 2

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(470, 154) = 36190

GCD(470, 154) = ( 470 x 154 ) / 36190

GCD(470, 154) = 72380 / 36190

GCD(470, 154) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 858

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

LCM(2, 858) = 858

GCD(2, 858) = ( 2 x 858 ) / 858

GCD(2, 858) = 1716 / 858

GCD(2, 858) = 2

GCD of 470, 154, 858 is 2
