Therefore, GCD of numbers 70, 205, 433, 660 is 1

Given Input Data is 70, 205, 433, 660

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

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 205 is 5 x 41

Prime Factorization of 433 is 433

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

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(70, 205) = 2870

GCD(70, 205) = ( 70 x 205 ) / 2870

GCD(70, 205) = 14350 / 2870

GCD(70, 205) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 433

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

LCM(5, 433) = 2165

GCD(5, 433) = ( 5 x 433 ) / 2165

GCD(5, 433) = 2165 / 2165

GCD(5, 433) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 660

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

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

GCD(1, 660) = 660 / 660

GCD(1, 660) = 1

GCD of 70, 205, 433, 660 is 1
