Therefore, GCD of numbers 685, 340, 11, 372 is 1

Given Input Data is 685, 340, 11, 372

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

Prime Factorization of 685 is 5 x 137

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

Prime Factorization of 11 is 11

Prime Factorization of 372 is 2 x 2 x 3 x 31

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(685, 340) = 46580

GCD(685, 340) = ( 685 x 340 ) / 46580

GCD(685, 340) = 232900 / 46580

GCD(685, 340) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 11

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

LCM(5, 11) = 55

GCD(5, 11) = ( 5 x 11 ) / 55

GCD(5, 11) = 55 / 55

GCD(5, 11) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 372

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

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

GCD(1, 372) = 372 / 372

GCD(1, 372) = 1

GCD of 685, 340, 11, 372 is 1
