Make use of GCD Calculator to determine the Greatest Common Divisor of 29, 78, 79 i.e. 1 largest integer that divides all the numbers equally.
GCD of 29, 78, 79 is 1
GCD(29, 78, 79) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 29, 78, 79 is 1
GCD(29, 78, 79) = 1
Given Input numbers are 29, 78, 79

1, 79
Greatest Common Divisior
We found the divisors of 29, 78, 79 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 29, 78, 79 is 1.
Therefore, GCD of numbers 29, 78, 79 is 1
Given Input Data is 29, 78, 79
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 29 is 29
Prime Factorization of 78 is 2 x 3 x 13
Prime Factorization of 79 is 79
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(29, 78) = 2262
GCD(29, 78) = ( 29 x 78 ) / 2262
GCD(29, 78) = 2262 / 2262
GCD(29, 78) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 79
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 79) = 79
GCD(1, 79) = ( 1 x 79 ) / 79
GCD(1, 79) = 79 / 79
GCD(1, 79) = 1
GCD of 29, 78, 79 is 1
