Make use of GCD Calculator to determine the Greatest Common Divisor of 785, 111, 17, 121 i.e. 1 largest integer that divides all the numbers equally.
GCD of 785, 111, 17, 121 is 1
GCD(785, 111, 17, 121) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 785, 111, 17, 121 is 1
GCD(785, 111, 17, 121) = 1
Given Input numbers are 785, 111, 17, 121
To find the GCD of numbers using factoring list out all the divisors of each number

1, 17
Divisors of 121
List of positive integer divisors of 121 that divides 121 without a remainder.
1, 11, 121
Greatest Common Divisior
We found the divisors of 785, 111, 17, 121 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 785, 111, 17, 121 is 1.
Therefore, GCD of numbers 785, 111, 17, 121 is 1
Given Input Data is 785, 111, 17, 121
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 785 is 5 x 157
Prime Factorization of 111 is 3 x 37
Prime Factorization of 17 is 17
Prime Factorization of 121 is 11 x 11
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(785, 111) = 87135
GCD(785, 111) = ( 785 x 111 ) / 87135
GCD(785, 111) = 87135 / 87135
GCD(785, 111) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 17
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 17) = 17
GCD(1, 17) = ( 1 x 17 ) / 17
GCD(1, 17) = 17 / 17
GCD(1, 17) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 121
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
GCD(1, 121) = 121 / 121
GCD(1, 121) = 1
GCD of 785, 111, 17, 121 is 1
