Therefore, GCD of numbers 155, 485, 923, 650 is 1

Given Input Data is 155, 485, 923, 650

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

Prime Factorization of 155 is 5 x 31

Prime Factorization of 485 is 5 x 97

Prime Factorization of 923 is 13 x 71

Prime Factorization of 650 is 2 x 5 x 5 x 13

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(155, 485) = 15035

GCD(155, 485) = ( 155 x 485 ) / 15035

GCD(155, 485) = 75175 / 15035

GCD(155, 485) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 923

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

LCM(5, 923) = 4615

GCD(5, 923) = ( 5 x 923 ) / 4615

GCD(5, 923) = 4615 / 4615

GCD(5, 923) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 650

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

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

GCD(1, 650) = 650 / 650

GCD(1, 650) = 1

GCD of 155, 485, 923, 650 is 1
