Make use of GCD Calculator to determine the Greatest Common Divisor of 11, 20, 86 i.e. 1 largest integer that divides all the numbers equally.
GCD of 11, 20, 86 is 1
GCD(11, 20, 86) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 11, 20, 86 is 1
GCD(11, 20, 86) = 1
Given Input numbers are 11, 20, 86
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 11
List of positive integer divisors of 11 that divides 11 without a remainder.
1, 11
Divisors of 20
List of positive integer divisors of 20 that divides 20 without a remainder.
1, 2, 4, 5, 10, 20
Divisors of 86
List of positive integer divisors of 86 that divides 86 without a remainder.
1, 2, 43, 86
Greatest Common Divisior
We found the divisors of 11, 20, 86 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 11, 20, 86 is 1.
Therefore, GCD of numbers 11, 20, 86 is 1
Given Input Data is 11, 20, 86
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 11 is 11
Prime Factorization of 20 is 2 x 2 x 5
Prime Factorization of 86 is 2 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(11, 20) = 220
GCD(11, 20) = ( 11 x 20 ) / 220
GCD(11, 20) = 220 / 220
GCD(11, 20) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 86
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 86) = 86
GCD(1, 86) = ( 1 x 86 ) / 86
GCD(1, 86) = 86 / 86
GCD(1, 86) = 1
GCD of 11, 20, 86 is 1
