Make use of GCD Calculator to determine the Greatest Common Divisor of 31, 81, 61 i.e. 1 largest integer that divides all the numbers equally.
GCD of 31, 81, 61 is 1
GCD(31, 81, 61) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 31, 81, 61 is 1
GCD(31, 81, 61) = 1
Given Input numbers are 31, 81, 61
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 31
List of positive integer divisors of 31 that divides 31 without a remainder.
1, 31
Divisors of 81
List of positive integer divisors of 81 that divides 81 without a remainder.
1, 3, 9, 27, 81
Divisors of 61
List of positive integer divisors of 61 that divides 61 without a remainder.
1, 61
Greatest Common Divisior
We found the divisors of 31, 81, 61 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 31, 81, 61 is 1.
Therefore, GCD of numbers 31, 81, 61 is 1
Given Input Data is 31, 81, 61
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 31 is 31
Prime Factorization of 81 is 3 x 3 x 3 x 3
Prime Factorization of 61 is 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(31, 81) = 2511
GCD(31, 81) = ( 31 x 81 ) / 2511
GCD(31, 81) = 2511 / 2511
GCD(31, 81) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 61
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 61) = 61
GCD(1, 61) = ( 1 x 61 ) / 61
GCD(1, 61) = 61 / 61
GCD(1, 61) = 1
GCD of 31, 81, 61 is 1
