Therefore, GCD of numbers 565, 215, 61, 853 is 1

Given Input Data is 565, 215, 61, 853

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

Prime Factorization of 565 is 5 x 113

Prime Factorization of 215 is 5 x 43

Prime Factorization of 61 is 61

Prime Factorization of 853 is 853

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(565, 215) = 24295

GCD(565, 215) = ( 565 x 215 ) / 24295

GCD(565, 215) = 121475 / 24295

GCD(565, 215) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 61

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

LCM(5, 61) = 305

GCD(5, 61) = ( 5 x 61 ) / 305

GCD(5, 61) = 305 / 305

GCD(5, 61) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 853

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

LCM(1, 853) = 853

GCD(1, 853) = ( 1 x 853 ) / 853

GCD(1, 853) = 853 / 853

GCD(1, 853) = 1

GCD of 565, 215, 61, 853 is 1
