Make use of GCD Calculator to determine the Greatest Common Divisor of 215, 441, 69, 161 i.e. 1 largest integer that divides all the numbers equally.
GCD of 215, 441, 69, 161 is 1
GCD(215, 441, 69, 161) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 215, 441, 69, 161 is 1
GCD(215, 441, 69, 161) = 1
Given Input numbers are 215, 441, 69, 161
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 23, 69
Divisors of 161
List of positive integer divisors of 161 that divides 161 without a remainder.
1, 7, 23, 161
Greatest Common Divisior
We found the divisors of 215, 441, 69, 161 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 215, 441, 69, 161 is 1.
Therefore, GCD of numbers 215, 441, 69, 161 is 1
Given Input Data is 215, 441, 69, 161
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 215 is 5 x 43
Prime Factorization of 441 is 3 x 3 x 7 x 7
Prime Factorization of 69 is 3 x 23
Prime Factorization of 161 is 7 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(215, 441) = 94815
GCD(215, 441) = ( 215 x 441 ) / 94815
GCD(215, 441) = 94815 / 94815
GCD(215, 441) = 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 161
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 161) = 161
GCD(1, 161) = ( 1 x 161 ) / 161
GCD(1, 161) = 161 / 161
GCD(1, 161) = 1
GCD of 215, 441, 69, 161 is 1
