Therefore, GCD of numbers 441, 177, 788, 245 is 1

Given Input Data is 441, 177, 788, 245

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

Prime Factorization of 441 is 3 x 3 x 7 x 7

Prime Factorization of 177 is 3 x 59

Prime Factorization of 788 is 2 x 2 x 197

Prime Factorization of 245 is 5 x 7 x 7

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(441, 177) = 26019

GCD(441, 177) = ( 441 x 177 ) / 26019

GCD(441, 177) = 78057 / 26019

GCD(441, 177) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 788

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

LCM(3, 788) = 2364

GCD(3, 788) = ( 3 x 788 ) / 2364

GCD(3, 788) = 2364 / 2364

GCD(3, 788) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 245

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

LCM(1, 245) = 245

GCD(1, 245) = ( 1 x 245 ) / 245

GCD(1, 245) = 245 / 245

GCD(1, 245) = 1

GCD of 441, 177, 788, 245 is 1
