Greatest Common Divisior
We found the divisors of 71, 9, 81, 71 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 71, 9, 81, 71 is 1.
Therefore, GCD of numbers 71, 9, 81, 71 is 1
Given Input Data is 71, 9, 81, 71
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 71 is 71
Prime Factorization of 9 is 3 x 3
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 71 is 71
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 71, 9, 81, 71 using LCM Formula
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(71, 9) = 639
GCD(71, 9) = ( 71 x 9 ) / 639
GCD(71, 9) = 639 / 639
GCD(71, 9) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 81
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 81) = 81
GCD(1, 81) = ( 1 x 81 ) / 81
GCD(1, 81) = 81 / 81
GCD(1, 81) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 71
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 71) = 71
GCD(1, 71) = ( 1 x 71 ) / 71
GCD(1, 71) = 71 / 71
GCD(1, 71) = 1
GCD of 71, 9, 81, 71 is 1
