Make use of GCD Calculator to determine the Greatest Common Divisor of 27, 521, 815, 315 i.e. 1 largest integer that divides all the numbers equally.
GCD of 27, 521, 815, 315 is 1
GCD(27, 521, 815, 315) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 27, 521, 815, 315 is 1
GCD(27, 521, 815, 315) = 1
Given Input numbers are 27, 521, 815, 315
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
Greatest Common Divisior
We found the divisors of 27, 521, 815, 315 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 27, 521, 815, 315 is 1.
Therefore, GCD of numbers 27, 521, 815, 315 is 1
Given Input Data is 27, 521, 815, 315
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 27 is 3 x 3 x 3
Prime Factorization of 521 is 521
Prime Factorization of 815 is 5 x 163
Prime Factorization of 315 is 3 x 3 x 5 x 7
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(27, 521) = 14067
GCD(27, 521) = ( 27 x 521 ) / 14067
GCD(27, 521) = 14067 / 14067
GCD(27, 521) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 815
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
GCD(1, 815) = 815 / 815
GCD(1, 815) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 315
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 315) = 315
GCD(1, 315) = ( 1 x 315 ) / 315
GCD(1, 315) = 315 / 315
GCD(1, 315) = 1
GCD of 27, 521, 815, 315 is 1
