Least Common Multiple (LCM) of 49 and 55 with the help of Prime Factorisation
One method for determining the LCM of 49 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 49's prime factorization:
| 7 | 49 |
| 7 | 7 |
| 1 |
Prime factors of 49 are 7.
49 = 72
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:7, 5,11
.51×72×111 = 2695
This shows that the LCM of 49 and 55 is 2695.
How to Calculate the LCM of 49 and 55 Using Common Multiples
The first step in determining the Least Common Multiple of 49 and 55 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 49 and 55:
Lets look at the first ten multiples of these numbers, 49 and 55:
49,98,147,196,245,294,343,392,441,833 are the first ten multiples of 49.
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 49 and 55, for example, are 588, 833, and 880. 2695 is the least common multiple since it is the smallest.
49 and 55 have an LCM of 2695.
Least Common Multiple of 49 and 55 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 49 and 55, than apply into the LCM equation.
GCF(49,55) = 1
LCM(49,55) = ( 49 × 55) / 1
LCM(49,55) = 2695 / 1
LCM(49,55) = 2695
