Make use of GCD Calculator to determine the Greatest Common Divisor of 115, 661, 747, 223 i.e. 1 largest integer that divides all the numbers equally.
GCD of 115, 661, 747, 223 is 1
GCD(115, 661, 747, 223) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 115, 661, 747, 223 is 1
GCD(115, 661, 747, 223) = 1
Given Input numbers are 115, 661, 747, 223
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 115, 661, 747, 223 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 115, 661, 747, 223 is 1.
Therefore, GCD of numbers 115, 661, 747, 223 is 1
Given Input Data is 115, 661, 747, 223
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 115 is 5 x 23
Prime Factorization of 661 is 661
Prime Factorization of 747 is 3 x 3 x 83
Prime Factorization of 223 is 223
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(115, 661) = 76015
GCD(115, 661) = ( 115 x 661 ) / 76015
GCD(115, 661) = 76015 / 76015
GCD(115, 661) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 747
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 747) = 747
GCD(1, 747) = ( 1 x 747 ) / 747
GCD(1, 747) = 747 / 747
GCD(1, 747) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 223
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 223) = 223
GCD(1, 223) = ( 1 x 223 ) / 223
GCD(1, 223) = 223 / 223
GCD(1, 223) = 1
GCD of 115, 661, 747, 223 is 1
