Make use of GCD Calculator to determine the Greatest Common Divisor of 13, 65, 73, 25 i.e. 1 largest integer that divides all the numbers equally.
GCD of 13, 65, 73, 25 is 1
GCD(13, 65, 73, 25) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 13, 65, 73, 25 is 1
GCD(13, 65, 73, 25) = 1
Given Input numbers are 13, 65, 73, 25
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 13, 65
Divisors of 73
List of positive integer divisors of 73 that divides 73 without a remainder.
1, 73
Divisors of 25
List of positive integer divisors of 25 that divides 25 without a remainder.
1, 5, 25
Greatest Common Divisior
We found the divisors of 13, 65, 73, 25 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 13, 65, 73, 25 is 1.
Therefore, GCD of numbers 13, 65, 73, 25 is 1
Given Input Data is 13, 65, 73, 25
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 13 is 13
Prime Factorization of 65 is 5 x 13
Prime Factorization of 73 is 73
Prime Factorization of 25 is 5 x 5
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(13, 65) = 65
GCD(13, 65) = ( 13 x 65 ) / 65
GCD(13, 65) = 845 / 65
GCD(13, 65) = 13
Step2:
Here we consider the GCD from the above i.e. 13 as first number and the next as 73
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(13, 73) = 949
GCD(13, 73) = ( 13 x 73 ) / 949
GCD(13, 73) = 949 / 949
GCD(13, 73) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 25
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 25) = 25
GCD(1, 25) = ( 1 x 25 ) / 25
GCD(1, 25) = 25 / 25
GCD(1, 25) = 1
GCD of 13, 65, 73, 25 is 1
