Therefore, GCD of numbers 195, 340, 29, 820 is 1

Given Input Data is 195, 340, 29, 820

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

Prime Factorization of 195 is 3 x 5 x 13

Prime Factorization of 340 is 2 x 2 x 5 x 17

Prime Factorization of 29 is 29

Prime Factorization of 820 is 2 x 2 x 5 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(195, 340) = 13260

GCD(195, 340) = ( 195 x 340 ) / 13260

GCD(195, 340) = 66300 / 13260

GCD(195, 340) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 29

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

LCM(5, 29) = 145

GCD(5, 29) = ( 5 x 29 ) / 145

GCD(5, 29) = 145 / 145

GCD(5, 29) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 820

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

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

GCD(1, 820) = 820 / 820

GCD(1, 820) = 1

GCD of 195, 340, 29, 820 is 1
