What is LCM of 9 and 16
Given Numbers are 9, 16
We can find the LCM of 9, 16 using the brute force method, prime factorization method, or GCD method.
To use brute force method, list the multiples of 9 and 16
Multiples of 9 =9,18,27,36,45,54,63,72,81,90,99,108,117,126,135,144,153,
Multiples of 16 =16,32,48,64,80,96,112,128,144,160,176,192,208,224,240,256,272,
Now, get the least common multiple of 9, 16 which is 144
So, the LCM of 9, 16 is 144.
Least Common Multiple (LCM) of 9 and 16 with the help of Prime Factorisation
One method for determining the LCM of 9 and 16 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 16's prime factorization:
| 2 | 16 |
| 2 | 8 |
| 2 | 4 |
| 2 | 2 |
| 1 |
Prime factors of 16 are 2.
16 = 24
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
.24×32 = 144
This shows that the LCM of 9 and 16 is 144.
How to Calculate the LCM of 9 and 16 Using Common Multiples
The first step in determining the Least Common Multiple of 9 and 16 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 9 and 16:
Lets look at the first ten multiples of these numbers, 9 and 16:
9,18,27,36,45,54,63,72,81,153 are the first ten multiples of 9.
16,32,48,64,80,96,112,128,144,272 are the first ten multiples of 16.
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 16, for example, are 108, 153, and 256. 144 is the least common multiple since it is the smallest.
9 and 16 have an LCM of 144.
Least Common Multiple of 9 and 16 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 16, than apply into the LCM equation.
GCF(9,16) = 1
LCM(9,16) = ( 9 × 16) / 1
LCM(9,16) = 144 / 1
LCM(9,16) = 144
