So, the LCM of 48, 55 is 2640.
One method for determining the LCM of 48 and 55 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 48's prime factorization:2 | 48 |
2 | 24 |
2 | 12 |
2 | 6 |
3 | 3 |
1 |
Prime factors of 48 are 2,3.
48 = 24×31
And this is 55's prime factorization:
5 | 55 |
11 | 11 |
1 |
Prime factors of 55 are 5,11.
55 = 51×111
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, 5,11
.24×31×51×111 = 2640
This shows that the LCM of 48 and 55 is 2640.
The first step in determining the Least Common Multiple of 48 and 55 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 48 and 55:
Lets look at the first ten multiples of these numbers, 48 and 55:
48,96,144,192,240,288,336,384,432,816 are the first ten multiples of 48.
55,110,165,220,275,330,385,440,495,935 are the first ten multiples of 55.
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 48 and 55, for example, are 576, 816, and 880. 2640 is the least common multiple since it is the smallest.
48 and 55 have an LCM of 2640.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 48 and 55, than apply into the LCM equation.
GCF(48,55) = 1
LCM(48,55) = ( 48 × 55) / 1
LCM(48,55) = 2640 / 1
LCM(48,55) = 2640
