Make use of GCD Calculator to determine the Greatest Common Divisor of 51, 79, 39 i.e. 1 largest integer that divides all the numbers equally.
GCD of 51, 79, 39 is 1
GCD(51, 79, 39) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 51, 79, 39 is 1
GCD(51, 79, 39) = 1
Given Input numbers are 51, 79, 39
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 51

1, 79
Divisors of 39
List of positive integer divisors of 39 that divides 39 without a remainder.
1, 3, 13, 39
Greatest Common Divisior
We found the divisors of 51, 79, 39 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 51, 79, 39 is 1.
Therefore, GCD of numbers 51, 79, 39 is 1
Given Input Data is 51, 79, 39
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 51 is 3 x 17
Prime Factorization of 79 is 79
Prime Factorization of 39 is 3 x 13
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(51, 79) = 4029
GCD(51, 79) = ( 51 x 79 ) / 4029
GCD(51, 79) = 4029 / 4029
GCD(51, 79) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 39
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 39) = 39
GCD(1, 39) = ( 1 x 39 ) / 39
GCD(1, 39) = 39 / 39
GCD(1, 39) = 1
GCD of 51, 79, 39 is 1
