Make use of GCD Calculator to determine the Greatest Common Divisor of 79, 9, 57, 18 i.e. 1 largest integer that divides all the numbers equally.
GCD of 79, 9, 57, 18 is 1
GCD(79, 9, 57, 18) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 79, 9, 57, 18 is 1
GCD(79, 9, 57, 18) = 1
Given Input numbers are 79, 9, 57, 18
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 3, 6, 9, 18
Greatest Common Divisior
We found the divisors of 79, 9, 57, 18 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 79, 9, 57, 18 is 1.
Therefore, GCD of numbers 79, 9, 57, 18 is 1
Given Input Data is 79, 9, 57, 18
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 79 is 79
Prime Factorization of 9 is 3 x 3
Prime Factorization of 57 is 3 x 19
Prime Factorization of 18 is 2 x 3 x 3
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(79, 9) = 711
GCD(79, 9) = ( 79 x 9 ) / 711
GCD(79, 9) = 711 / 711
GCD(79, 9) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 57
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 57) = 57
GCD(1, 57) = ( 1 x 57 ) / 57
GCD(1, 57) = 57 / 57
GCD(1, 57) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 18
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 18) = 18
GCD(1, 18) = ( 1 x 18 ) / 18
GCD(1, 18) = 18 / 18
GCD(1, 18) = 1
GCD of 79, 9, 57, 18 is 1
