Make use of GCD Calculator to determine the Greatest Common Divisor of 245, 961, 18, 671 i.e. 1 largest integer that divides all the numbers equally.
GCD of 245, 961, 18, 671 is 1
GCD(245, 961, 18, 671) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 245, 961, 18, 671 is 1
GCD(245, 961, 18, 671) = 1
Given Input numbers are 245, 961, 18, 671
To find the GCD of numbers using factoring list out all the divisors of each number

1, 11, 61, 671
Greatest Common Divisior
We found the divisors of 245, 961, 18, 671 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 245, 961, 18, 671 is 1.
Therefore, GCD of numbers 245, 961, 18, 671 is 1
Given Input Data is 245, 961, 18, 671
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 245 is 5 x 7 x 7
Prime Factorization of 961 is 31 x 31
Prime Factorization of 18 is 2 x 3 x 3
Prime Factorization of 671 is 11 x 61
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(245, 961) = 235445
GCD(245, 961) = ( 245 x 961 ) / 235445
GCD(245, 961) = 235445 / 235445
GCD(245, 961) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 18
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 18) = 18
GCD(1, 18) = ( 1 x 18 ) / 18
GCD(1, 18) = 18 / 18
GCD(1, 18) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 671
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 671) = 671
GCD(1, 671) = ( 1 x 671 ) / 671
GCD(1, 671) = 671 / 671
GCD(1, 671) = 1
GCD of 245, 961, 18, 671 is 1
