Therefore, GCD of numbers 395, 325, 86, 670 is 1

Given Input Data is 395, 325, 86, 670

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

Prime Factorization of 395 is 5 x 79

Prime Factorization of 325 is 5 x 5 x 13

Prime Factorization of 86 is 2 x 43

Prime Factorization of 670 is 2 x 5 x 67

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(395, 325) = 25675

GCD(395, 325) = ( 395 x 325 ) / 25675

GCD(395, 325) = 128375 / 25675

GCD(395, 325) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 86

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

LCM(5, 86) = 430

GCD(5, 86) = ( 5 x 86 ) / 430

GCD(5, 86) = 430 / 430

GCD(5, 86) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 670

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

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

GCD(1, 670) = 670 / 670

GCD(1, 670) = 1

GCD of 395, 325, 86, 670 is 1
