Make use of GCD Calculator to determine the Greatest Common Divisor of 7, 27, 89 i.e. 1 largest integer that divides all the numbers equally.
GCD of 7, 27, 89 is 1
GCD(7, 27, 89) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 7, 27, 89 is 1
GCD(7, 27, 89) = 1
Given Input numbers are 7, 27, 89
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 7

1, 89
Greatest Common Divisior
We found the divisors of 7, 27, 89 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 7, 27, 89 is 1.
Therefore, GCD of numbers 7, 27, 89 is 1
Given Input Data is 7, 27, 89
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 7 is 7
Prime Factorization of 27 is 3 x 3 x 3
Prime Factorization of 89 is 89
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(7, 27) = 189
GCD(7, 27) = ( 7 x 27 ) / 189
GCD(7, 27) = 189 / 189
GCD(7, 27) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 89
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 89) = 89
GCD(1, 89) = ( 1 x 89 ) / 89
GCD(1, 89) = 89 / 89
GCD(1, 89) = 1
GCD of 7, 27, 89 is 1
