Therefore, GCD of numbers 646, 722, 41, 170 is 1

Given Input Data is 646, 722, 41, 170

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

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 722 is 2 x 19 x 19

Prime Factorization of 41 is 41

Prime Factorization of 170 is 2 x 5 x 17

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(646, 722) = 12274

GCD(646, 722) = ( 646 x 722 ) / 12274

GCD(646, 722) = 466412 / 12274

GCD(646, 722) = 38

Step2:

Here we consider the GCD from the above i.e. 38 as first number and the next as 41

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

LCM(38, 41) = 1558

GCD(38, 41) = ( 38 x 41 ) / 1558

GCD(38, 41) = 1558 / 1558

GCD(38, 41) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 170

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

LCM(1, 170) = 170

GCD(1, 170) = ( 1 x 170 ) / 170

GCD(1, 170) = 170 / 170

GCD(1, 170) = 1

GCD of 646, 722, 41, 170 is 1
