Given Input Data is 870, 995, 620

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

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 995 is 5 x 199

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

Highest common occurrences in the given inputs are 5¹

Multiplying them we get the GCD as 5

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(870, 995) = 173130

GCD(870, 995) = ( 870 x 995 ) / 173130

GCD(870, 995) = 865650 / 173130

GCD(870, 995) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 620

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

LCM(5, 620) = 620

GCD(5, 620) = ( 5 x 620 ) / 620

GCD(5, 620) = 3100 / 620

GCD(5, 620) = 5

GCD of 870, 995, 620 is 5
