Therefore, GCD of numbers 25, 620, 225, 229 is 1

Given Input Data is 25, 620, 225, 229

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

Prime Factorization of 25 is 5 x 5

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

Prime Factorization of 225 is 3 x 3 x 5 x 5

Prime Factorization of 229 is 229

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(25, 620) = 3100

GCD(25, 620) = ( 25 x 620 ) / 3100

GCD(25, 620) = 15500 / 3100

GCD(25, 620) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 225

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

LCM(5, 225) = 225

GCD(5, 225) = ( 5 x 225 ) / 225

GCD(5, 225) = 1125 / 225

GCD(5, 225) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 229

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

LCM(5, 229) = 1145

GCD(5, 229) = ( 5 x 229 ) / 1145

GCD(5, 229) = 1145 / 1145

GCD(5, 229) = 1

GCD of 25, 620, 225, 229 is 1
