Therefore, GCD of numbers 164, 964, 325, 685 is 1

Given Input Data is 164, 964, 325, 685

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

Prime Factorization of 164 is 2 x 2 x 41

Prime Factorization of 964 is 2 x 2 x 241

Prime Factorization of 325 is 5 x 5 x 13

Prime Factorization of 685 is 5 x 137

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(164, 964) = 39524

GCD(164, 964) = ( 164 x 964 ) / 39524

GCD(164, 964) = 158096 / 39524

GCD(164, 964) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 325

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

LCM(4, 325) = 1300

GCD(4, 325) = ( 4 x 325 ) / 1300

GCD(4, 325) = 1300 / 1300

GCD(4, 325) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 685

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

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

GCD(1, 685) = 685 / 685

GCD(1, 685) = 1

GCD of 164, 964, 325, 685 is 1
