Given Input Data is 78, 936, 170, 620

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

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 936 is 2 x 2 x 2 x 3 x 3 x 13

Prime Factorization of 170 is 2 x 5 x 17

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

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(78, 936) = 936

GCD(78, 936) = ( 78 x 936 ) / 936

GCD(78, 936) = 73008 / 936

GCD(78, 936) = 78

Step2:

Here we consider the GCD from the above i.e. 78 as first number and the next as 170

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

LCM(78, 170) = 6630

GCD(78, 170) = ( 78 x 170 ) / 6630

GCD(78, 170) = 13260 / 6630

GCD(78, 170) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 620

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

LCM(2, 620) = 620

GCD(2, 620) = ( 2 x 620 ) / 620

GCD(2, 620) = 1240 / 620

GCD(2, 620) = 2

GCD of 78, 936, 170, 620 is 2
