Make use of GCD Calculator to determine the Greatest Common Divisor of 89, 70, 11, 66 i.e. 1 largest integer that divides all the numbers equally.
GCD of 89, 70, 11, 66 is 1
GCD(89, 70, 11, 66) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 89, 70, 11, 66 is 1
GCD(89, 70, 11, 66) = 1
Given Input numbers are 89, 70, 11, 66
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 89
List of positive integer divisors of 89 that divides 89 without a remainder.
1, 89
Divisors of 70

1, 2, 5, 7, 10, 14, 35, 70
Divisors of 11
List of positive integer divisors of 11 that divides 11 without a remainder.
1, 11
Divisors of 66
List of positive integer divisors of 66 that divides 66 without a remainder.
1, 2, 3, 6, 11, 22, 33, 66
Greatest Common Divisior
We found the divisors of 89, 70, 11, 66 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 89, 70, 11, 66 is 1.
Therefore, GCD of numbers 89, 70, 11, 66 is 1
Given Input Data is 89, 70, 11, 66
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 89 is 89
Prime Factorization of 70 is 2 x 5 x 7
Prime Factorization of 11 is 11
Prime Factorization of 66 is 2 x 3 x 11
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(89, 70) = 6230
GCD(89, 70) = ( 89 x 70 ) / 6230
GCD(89, 70) = 6230 / 6230
GCD(89, 70) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 11
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 11) = 11
GCD(1, 11) = ( 1 x 11 ) / 11
GCD(1, 11) = 11 / 11
GCD(1, 11) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 66
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 66) = 66
GCD(1, 66) = ( 1 x 66 ) / 66
GCD(1, 66) = 66 / 66
GCD(1, 66) = 1
GCD of 89, 70, 11, 66 is 1
