One method for determining the LCM of 128 and 132 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 128's prime factorization:2 | 128 |
2 | 64 |
2 | 32 |
2 | 16 |
2 | 8 |
2 | 4 |
2 | 2 |
1 |
Prime factors of 128 are 2.
128 = 27
And this is 132's prime factorization:
2 | 132 |
2 | 66 |
3 | 33 |
11 | 11 |
1 |
Prime factors of 132 are 2, 3,11.
132 = 22×31×111
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:2, 3,11
.27×31×111 = 4224
This shows that the LCM of 128 and 132 is 4224.
The first step in determining the Least Common Multiple of 128 and 132 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 128 and 132:
Lets look at the first ten multiples of these numbers, 128 and 132:
128,256,384,512,640,768,896,1024,1152,2176 are the first ten multiples of 128.
132,264,396,528,660,792,924,1056,1188,2244 are the first ten multiples of 132.
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 128 and 132, for example, are 1536, 2176, and 2112. 4224 is the least common multiple since it is the smallest.
128 and 132 have an LCM of 4224.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 128 and 132, than apply into the LCM equation.
GCF(128,132) = 4
LCM(128,132) = ( 128 × 132) / 4
LCM(128,132) = 16896 / 4
LCM(128,132) = 4224
