Given Input Data is 390, 920, 334

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

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

Prime Factorization of 334 is 2 x 167

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(390, 920) = 35880

GCD(390, 920) = ( 390 x 920 ) / 35880

GCD(390, 920) = 358800 / 35880

GCD(390, 920) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 334

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

LCM(10, 334) = 1670

GCD(10, 334) = ( 10 x 334 ) / 1670

GCD(10, 334) = 3340 / 1670

GCD(10, 334) = 2

GCD of 390, 920, 334 is 2
