Given Input Data is 244, 402, 40, 878

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

Prime Factorization of 244 is 2 x 2 x 61

Prime Factorization of 402 is 2 x 3 x 67

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 878 is 2 x 439

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(244, 402) = 49044

GCD(244, 402) = ( 244 x 402 ) / 49044

GCD(244, 402) = 98088 / 49044

GCD(244, 402) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 40

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

LCM(2, 40) = 40

GCD(2, 40) = ( 2 x 40 ) / 40

GCD(2, 40) = 80 / 40

GCD(2, 40) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 878

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

LCM(2, 878) = 878

GCD(2, 878) = ( 2 x 878 ) / 878

GCD(2, 878) = 1756 / 878

GCD(2, 878) = 2

GCD of 244, 402, 40, 878 is 2
