What is LCM of 17 and 22
Given Numbers are 17, 22
We can find the LCM of 17, 22 using the brute force method, prime factorization method, or GCD method.
To use brute force method, list the multiples of 17 and 22
Multiples of 17 =17,34,51,68,85,102,119,136,153,170,187,204,221,238,255,272,289,
Multiples of 22 =22,44,66,88,110,132,154,176,198,220,242,264,286,308,330,352,374,
Now, get the least common multiple of 17, 22 which is 374
So, the LCM of 17, 22 is 374.
Least Common Multiple (LCM) of 17 and 22 with the help of Prime Factorisation
One method for determining the LCM of 17 and 22 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 17's prime factorization:
| 17 | 17 |
| 1 |
Prime factors of 17 are 17.
17 = 171
And this is 22's prime factorization:
| 2 | 22 |
| 11 | 11 |
| 1 |
Prime factors of 22 are 2,11.
22 = 21×111
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:17, 2,11
.21×111×171 = 374
This shows that the LCM of 17 and 22 is 374.
How to Calculate the LCM of 17 and 22 Using Common Multiples
The first step in determining the Least Common Multiple of 17 and 22 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 17 and 22:
Lets look at the first ten multiples of these numbers, 17 and 22:
17,34,51,68,85,102,119,136,153,289 are the first ten multiples of 17.
22,44,66,88,110,132,154,176,198,374 are the first ten multiples of 22.
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 17 and 22, for example, are 204, 289, and 352. 374 is the least common multiple since it is the smallest.
17 and 22 have an LCM of 374.
Least Common Multiple of 17 and 22 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 17 and 22, than apply into the LCM equation.
GCF(17,22) = 1
LCM(17,22) = ( 17 × 22) / 1
LCM(17,22) = 374 / 1
LCM(17,22) = 374
