Therefore, GCD of numbers 620, 995, 40, 164 is 1

Given Input Data is 620, 995, 40, 164

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

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

Prime Factorization of 995 is 5 x 199

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

Prime Factorization of 164 is 2 x 2 x 41

The above numbers do not have any common prime factor. So GCD is 1

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(620, 995) = 123380

GCD(620, 995) = ( 620 x 995 ) / 123380

GCD(620, 995) = 616900 / 123380

GCD(620, 995) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 40

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

LCM(5, 40) = 40

GCD(5, 40) = ( 5 x 40 ) / 40

GCD(5, 40) = 200 / 40

GCD(5, 40) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 164

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

LCM(5, 164) = 820

GCD(5, 164) = ( 5 x 164 ) / 820

GCD(5, 164) = 820 / 820

GCD(5, 164) = 1

GCD of 620, 995, 40, 164 is 1
