Make use of GCD Calculator to determine the Greatest Common Divisor of 920, 929, 69, 345 i.e. 1 largest integer that divides all the numbers equally.
GCD of 920, 929, 69, 345 is 1
GCD(920, 929, 69, 345) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 920, 929, 69, 345 is 1
GCD(920, 929, 69, 345) = 1
Given Input numbers are 920, 929, 69, 345
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 920

1, 3, 23, 69
Divisors of 345
List of positive integer divisors of 345 that divides 345 without a remainder.
1, 3, 5, 15, 23, 69, 115, 345
Greatest Common Divisior
We found the divisors of 920, 929, 69, 345 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 920, 929, 69, 345 is 1.
Therefore, GCD of numbers 920, 929, 69, 345 is 1
Given Input Data is 920, 929, 69, 345
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23
Prime Factorization of 929 is 929
Prime Factorization of 69 is 3 x 23
Prime Factorization of 345 is 3 x 5 x 23
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(920, 929) = 854680
GCD(920, 929) = ( 920 x 929 ) / 854680
GCD(920, 929) = 854680 / 854680
GCD(920, 929) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 69
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 69) = 69
GCD(1, 69) = ( 1 x 69 ) / 69
GCD(1, 69) = 69 / 69
GCD(1, 69) = 1
Step3:
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
GCD of 920, 929, 69, 345 is 1
