So, the LCM of 46, 51 is 2346.
Least Common Multiple (LCM) of 46 and 51 with the help of Prime Factorisation
One method for determining the LCM of 46 and 51 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 46's prime factorization:
| 2 | 46 |
| 23 | 23 |
| 1 |
Prime factors of 46 are 2,23.
46 = 21×231
And this is 51's prime factorization:
| 3 | 51 |
| 17 | 17 |
| 1 |
Prime factors of 51 are 3,17.
51 = 31×171
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: 2,23, 3,17
.21×31×171×231 = 2346
This shows that the LCM of 46 and 51 is 2346.
How to Calculate the LCM of 46 and 51 Using Common Multiples
The first step in determining the Least Common Multiple of 46 and 51 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 46 and 51:
Lets look at the first ten multiples of these numbers, 46 and 51:
46,92,138,184,230,276,322,368,414,782 are the first ten multiples of 46.
51,102,153,204,255,306,357,408,459,867 are the first ten multiples of 51.
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 46 and 51, for example, are 552, 782, and 816. 2346 is the least common multiple since it is the smallest.
46 and 51 have an LCM of 2346.
Least Common Multiple of 46 and 51 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 46 and 51, than apply into the LCM equation.
GCF(46,51) = 1
LCM(46,51) = ( 46 × 51) / 1
LCM(46,51) = 2346 / 1
LCM(46,51) = 2346
