What is LCM of 9 and 14
Given Numbers are 9, 14
We can find the LCM of 9, 14 using the brute force method, prime factorization method, or GCD method.
To use brute force method, list the multiples of 9 and 14
Multiples of 9 =9,18,27,36,45,54,63,72,81,90,99,108,117,126,135,144,153,
Multiples of 14 =14,28,42,56,70,84,98,112,126,140,154,168,182,196,210,224,238,
Now, get the least common multiple of 9, 14 which is 126
So, the LCM of 9, 14 is 126.
Least Common Multiple (LCM) of 9 and 14 with the help of Prime Factorisation
One method for determining the LCM of 9 and 14 is to compare the prime factorization of each number. You can find the prime factorization for each number by following the instructions below:
Here is 9's prime factorization:
| 3 | 9 |
| 3 | 3 |
| 1 |
Prime factors of 9 are 3.
9 = 32
And this is 14's prime factorization:
| 2 | 14 |
| 7 | 7 |
| 1 |
Prime factors of 14 are 2,7.
14 = 21×71
When comparing the prime factorization of these two numbers, look for the highest power to which each prime factor is raised. In this case, the following primary factors must be considered:3, 2,7
.21×32×71 = 126
This shows that the LCM of 9 and 14 is 126.
How to Calculate the LCM of 9 and 14 Using Common Multiples
The first step in determining the Least Common Multiple of 9 and 14 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 9 and 14:
Lets look at the first ten multiples of these numbers, 9 and 14:
9,18,27,36,45,54,63,72,81,153 are the first ten multiples of 9.
14,28,42,56,70,84,98,112,126,238 are the first ten multiples of 14.
You can continue to list the multiples of these numbers until you find a match. Once you have found a match, or several matches, the Least Common Multiple is the smallest of these matches. The first matching multiple(s) of 9 and 14, for example, are 108, 153, and 224. 126 is the least common multiple since it is the smallest.
9 and 14 have an LCM of 126.
Least Common Multiple of 9 and 14 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 9 and 14, than apply into the LCM equation.
GCF(9,14) = 1
LCM(9,14) = ( 9 × 14) / 1
LCM(9,14) = 126 / 1
LCM(9,14) = 126
