We found the divisors of 340, 415, 335, 128 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 340, 415, 335, 128 is 1.

Therefore, GCD of numbers 340, 415, 335, 128 is 1

Given Input Data is 340, 415, 335, 128

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

Prime Factorization of 340 is 2 x 2 x 5 x 17

Prime Factorization of 415 is 5 x 83

Prime Factorization of 335 is 5 x 67

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

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(340, 415) = 28220

GCD(340, 415) = ( 340 x 415 ) / 28220

GCD(340, 415) = 141100 / 28220

GCD(340, 415) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 335

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

LCM(5, 335) = 335

GCD(5, 335) = ( 5 x 335 ) / 335

GCD(5, 335) = 1675 / 335

GCD(5, 335) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 128

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

LCM(5, 128) = 640

GCD(5, 128) = ( 5 x 128 ) / 640

GCD(5, 128) = 640 / 640

GCD(5, 128) = 1

GCD of 340, 415, 335, 128 is 1
