Therefore, GCD of numbers 511, 770, 71, 168 is 1

Given Input Data is 511, 770, 71, 168

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

Prime Factorization of 511 is 7 x 73

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 71 is 71

Prime Factorization of 168 is 2 x 2 x 2 x 3 x 7

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(511, 770) = 56210

GCD(511, 770) = ( 511 x 770 ) / 56210

GCD(511, 770) = 393470 / 56210

GCD(511, 770) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 71

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

LCM(7, 71) = 497

GCD(7, 71) = ( 7 x 71 ) / 497

GCD(7, 71) = 497 / 497

GCD(7, 71) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 168

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

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

GCD(1, 168) = 168 / 168

GCD(1, 168) = 1

GCD of 511, 770, 71, 168 is 1
