Therefore, GCD of numbers 128, 660, 433, 265 is 1

Given Input Data is 128, 660, 433, 265

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

Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2

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

Prime Factorization of 433 is 433

Prime Factorization of 265 is 5 x 53

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(128, 660) = 21120

GCD(128, 660) = ( 128 x 660 ) / 21120

GCD(128, 660) = 84480 / 21120

GCD(128, 660) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 433

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

LCM(4, 433) = 1732

GCD(4, 433) = ( 4 x 433 ) / 1732

GCD(4, 433) = 1732 / 1732

GCD(4, 433) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 265

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

LCM(1, 265) = 265

GCD(1, 265) = ( 1 x 265 ) / 265

GCD(1, 265) = 265 / 265

GCD(1, 265) = 1

GCD of 128, 660, 433, 265 is 1
