Make use of GCD Calculator to determine the Greatest Common Divisor of 247, 330, 13, 120 i.e. 1 largest integer that divides all the numbers equally.
GCD of 247, 330, 13, 120 is 1
GCD(247, 330, 13, 120) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 247, 330, 13, 120 is 1
GCD(247, 330, 13, 120) = 1
Given Input numbers are 247, 330, 13, 120
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 247

1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
Greatest Common Divisior
We found the divisors of 247, 330, 13, 120 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 247, 330, 13, 120 is 1.
Therefore, GCD of numbers 247, 330, 13, 120 is 1
Given Input Data is 247, 330, 13, 120
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 247 is 13 x 19
Prime Factorization of 330 is 2 x 3 x 5 x 11
Prime Factorization of 13 is 13
Prime Factorization of 120 is 2 x 2 x 2 x 3 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(247, 330) = 81510
GCD(247, 330) = ( 247 x 330 ) / 81510
GCD(247, 330) = 81510 / 81510
GCD(247, 330) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 13
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 13) = 13
GCD(1, 13) = ( 1 x 13 ) / 13
GCD(1, 13) = 13 / 13
GCD(1, 13) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 120
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 120) = 120
GCD(1, 120) = ( 1 x 120 ) / 120
GCD(1, 120) = 120 / 120
GCD(1, 120) = 1
GCD of 247, 330, 13, 120 is 1
