We found the divisors of 154, 115, 69, 472 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 154, 115, 69, 472 is 1.

Therefore, GCD of numbers 154, 115, 69, 472 is 1

Given Input Data is 154, 115, 69, 472

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

Prime Factorization of 154 is 2 x 7 x 11

Prime Factorization of 115 is 5 x 23

Prime Factorization of 69 is 3 x 23

Prime Factorization of 472 is 2 x 2 x 2 x 59

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(154, 115) = 17710

GCD(154, 115) = ( 154 x 115 ) / 17710

GCD(154, 115) = 17710 / 17710

GCD(154, 115) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 69

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

LCM(1, 69) = 69

GCD(1, 69) = ( 1 x 69 ) / 69

GCD(1, 69) = 69 / 69

GCD(1, 69) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 472

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

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

GCD(1, 472) = 472 / 472

GCD(1, 472) = 1

GCD of 154, 115, 69, 472 is 1
