Make use of GCD Calculator to determine the Greatest Common Divisor of 48, 30, 18 i.e. 6 largest integer that divides all the numbers equally.
GCD of 48, 30, 18 is 6
GCD(48, 30, 18) = 6
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 48, 30, 18 is 6
GCD(48, 30, 18) = 6
Given Input numbers are 48, 30, 18
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 48
List of positive integer divisors of 48 that divides 48 without a remainder.
1, 2, 3, 4, 6, 8, 12, 16, 24, 48
Divisors of 30
List of positive integer divisors of 30 that divides 30 without a remainder.
1, 2, 3, 5, 6, 10, 15, 30
Divisors of 18
List of positive integer divisors of 18 that divides 18 without a remainder.
1, 2, 3, 6, 9, 18
Greatest Common Divisior
We found the divisors of 48, 30, 18 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 48, 30, 18 is 6.
Therefore, GCD of numbers 48, 30, 18 is 6
Given Input Data is 48, 30, 18
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 48 is 2 x 2 x 2 x 2 x 3
Prime Factorization of 30 is 2 x 3 x 5
Prime Factorization of 18 is 2 x 3 x 3
Highest common occurrences in the given inputs are 21 x 31
Multiplying them we get the GCD as 6
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(48, 30) = 240
GCD(48, 30) = ( 48 x 30 ) / 240
GCD(48, 30) = 1440 / 240
GCD(48, 30) = 6
Step2:
Here we consider the GCD from the above i.e. 6 as first number and the next as 18
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(6, 18) = 18
GCD(6, 18) = ( 6 x 18 ) / 18
GCD(6, 18) = 108 / 18
GCD(6, 18) = 6
GCD of 48, 30, 18 is 6
