Make use of GCD Calculator to determine the Greatest Common Divisor of 815, 313, 154, 625 i.e. 1 largest integer that divides all the numbers equally.
GCD of 815, 313, 154, 625 is 1
GCD(815, 313, 154, 625) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 815, 313, 154, 625 is 1
GCD(815, 313, 154, 625) = 1
Given Input numbers are 815, 313, 154, 625
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 815, 313, 154, 625 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 815, 313, 154, 625 is 1.
Therefore, GCD of numbers 815, 313, 154, 625 is 1
Given Input Data is 815, 313, 154, 625
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 815 is 5 x 163
Prime Factorization of 313 is 313
Prime Factorization of 154 is 2 x 7 x 11
Prime Factorization of 625 is 5 x 5 x 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(815, 313) = 255095
GCD(815, 313) = ( 815 x 313 ) / 255095
GCD(815, 313) = 255095 / 255095
GCD(815, 313) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 154
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
GCD(1, 154) = 154 / 154
GCD(1, 154) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 625
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 625) = 625
GCD(1, 625) = ( 1 x 625 ) / 625
GCD(1, 625) = 625 / 625
GCD(1, 625) = 1
GCD of 815, 313, 154, 625 is 1
