Make use of GCD Calculator to determine the Greatest Common Divisor of 391, 293, 345, 581 i.e. 1 largest integer that divides all the numbers equally.
GCD of 391, 293, 345, 581 is 1
GCD(391, 293, 345, 581) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 391, 293, 345, 581 is 1
GCD(391, 293, 345, 581) = 1
Given Input numbers are 391, 293, 345, 581
To find the GCD of numbers using factoring list out all the divisors of each number

1, 7, 83, 581
Greatest Common Divisior
We found the divisors of 391, 293, 345, 581 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 391, 293, 345, 581 is 1.
Therefore, GCD of numbers 391, 293, 345, 581 is 1
Given Input Data is 391, 293, 345, 581
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 391 is 17 x 23
Prime Factorization of 293 is 293
Prime Factorization of 345 is 3 x 5 x 23
Prime Factorization of 581 is 7 x 83
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(391, 293) = 114563
GCD(391, 293) = ( 391 x 293 ) / 114563
GCD(391, 293) = 114563 / 114563
GCD(391, 293) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 345
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 345) = 345
GCD(1, 345) = ( 1 x 345 ) / 345
GCD(1, 345) = 345 / 345
GCD(1, 345) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 581
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 581) = 581
GCD(1, 581) = ( 1 x 581 ) / 581
GCD(1, 581) = 581 / 581
GCD(1, 581) = 1
GCD of 391, 293, 345, 581 is 1
