Therefore, GCD of numbers 830, 115, 26, 565 is 1

Given Input Data is 830, 115, 26, 565

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

Prime Factorization of 830 is 2 x 5 x 83

Prime Factorization of 115 is 5 x 23

Prime Factorization of 26 is 2 x 13

Prime Factorization of 565 is 5 x 113

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(830, 115) = 19090

GCD(830, 115) = ( 830 x 115 ) / 19090

GCD(830, 115) = 95450 / 19090

GCD(830, 115) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 26

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

LCM(5, 26) = 130

GCD(5, 26) = ( 5 x 26 ) / 130

GCD(5, 26) = 130 / 130

GCD(5, 26) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 565

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

LCM(1, 565) = 565

GCD(1, 565) = ( 1 x 565 ) / 565

GCD(1, 565) = 565 / 565

GCD(1, 565) = 1

GCD of 830, 115, 26, 565 is 1
