We found the divisors of 80, 851, 145, 729 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 80, 851, 145, 729 is 1.

Therefore, GCD of numbers 80, 851, 145, 729 is 1

Given Input Data is 80, 851, 145, 729

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

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 851 is 23 x 37

Prime Factorization of 145 is 5 x 29

Prime Factorization of 729 is 3 x 3 x 3 x 3 x 3 x 3

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(80, 851) = 68080

GCD(80, 851) = ( 80 x 851 ) / 68080

GCD(80, 851) = 68080 / 68080

GCD(80, 851) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 145

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

LCM(1, 145) = 145

GCD(1, 145) = ( 1 x 145 ) / 145

GCD(1, 145) = 145 / 145

GCD(1, 145) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 729

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

LCM(1, 729) = 729

GCD(1, 729) = ( 1 x 729 ) / 729

GCD(1, 729) = 729 / 729

GCD(1, 729) = 1

GCD of 80, 851, 145, 729 is 1
