So, the LCM of 55, 63 is 3465.
Least Common Multiple (LCM) of 55 and 63 with the help of Prime Factorisation
One method for determining the LCM of 55 and 63 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 55's prime factorization:
| 5 | 55 |
| 11 | 11 |
| 1 |
Prime factors of 55 are 5,11.
55 = 51×111
And this is 63's prime factorization:
| 3 | 63 |
| 3 | 21 |
| 7 | 7 |
| 1 |
Prime factors of 63 are 3,7.
63 = 32×71
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: 5,11, 3,7
.32×51×71×111 = 3465
This shows that the LCM of 55 and 63 is 3465.
How to Calculate the LCM of 55 and 63 Using Common Multiples
The first step in determining the Least Common Multiple of 55 and 63 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 55 and 63:
Lets look at the first ten multiples of these numbers, 55 and 63:
55,110,165,220,275,330,385,440,495,935 are the first ten multiples of 55.
63,126,189,252,315,378,441,504,567,1071 are the first ten multiples of 63.
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 55 and 63, for example, are 660, 935, and 1008. 3465 is the least common multiple since it is the smallest.
55 and 63 have an LCM of 3465.
Least Common Multiple of 55 and 63 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 55 and 63, than apply into the LCM equation.
GCF(55,63) = 1
LCM(55,63) = ( 55 × 63) / 1
LCM(55,63) = 3465 / 1
LCM(55,63) = 3465
