We found the divisors of 143, 163, 134, 645 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 143, 163, 134, 645 is 1.

Therefore, GCD of numbers 143, 163, 134, 645 is 1

Given Input Data is 143, 163, 134, 645

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

Prime Factorization of 143 is 11 x 13

Prime Factorization of 163 is 163

Prime Factorization of 134 is 2 x 67

Prime Factorization of 645 is 3 x 5 x 43

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(143, 163) = 23309

GCD(143, 163) = ( 143 x 163 ) / 23309

GCD(143, 163) = 23309 / 23309

GCD(143, 163) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 134

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

LCM(1, 134) = 134

GCD(1, 134) = ( 1 x 134 ) / 134

GCD(1, 134) = 134 / 134

GCD(1, 134) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 645

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

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

GCD(1, 645) = 645 / 645

GCD(1, 645) = 1

GCD of 143, 163, 134, 645 is 1
