Make use of GCD Calculator to determine the Greatest Common Divisor of 65, 17, 85 i.e. 1 largest integer that divides all the numbers equally.
GCD of 65, 17, 85 is 1
GCD(65, 17, 85) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 65, 17, 85 is 1
GCD(65, 17, 85) = 1
Given Input numbers are 65, 17, 85
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 65

1, 17
Divisors of 85
List of positive integer divisors of 85 that divides 85 without a remainder.
1, 5, 17, 85
Greatest Common Divisior
We found the divisors of 65, 17, 85 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 65, 17, 85 is 1.
Therefore, GCD of numbers 65, 17, 85 is 1
Given Input Data is 65, 17, 85
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 65 is 5 x 13
Prime Factorization of 17 is 17
Prime Factorization of 85 is 5 x 17
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(65, 17) = 1105
GCD(65, 17) = ( 65 x 17 ) / 1105
GCD(65, 17) = 1105 / 1105
GCD(65, 17) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 85
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 85) = 85
GCD(1, 85) = ( 1 x 85 ) / 85
GCD(1, 85) = 85 / 85
GCD(1, 85) = 1
GCD of 65, 17, 85 is 1
