So, the LCM of 66, 73 is 4818.
Least Common Multiple (LCM) of 66 and 73 with the help of Prime Factorisation
One method for determining the LCM of 66 and 73 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 66's prime factorization:
| 2 | 66 |
| 3 | 33 |
| 11 | 11 |
| 1 |
Prime factors of 66 are 2, 3,11.
66 = 21×31×111
And this is 73's prime factorization:
| 73 | 73 |
| 1 |
Prime factors of 73 are 73.
73 = 731
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, 3,11,73
.21×31×111×731 = 4818
This shows that the LCM of 66 and 73 is 4818.
How to Calculate the LCM of 66 and 73 Using Common Multiples
The first step in determining the Least Common Multiple of 66 and 73 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 66 and 73:
Lets look at the first ten multiples of these numbers, 66 and 73:
66,132,198,264,330,396,462,528,594,1122 are the first ten multiples of 66.
73,146,219,292,365,438,511,584,657,1241 are the first ten multiples of 73.
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 66 and 73, for example, are 792, 1122, and 1168. 4818 is the least common multiple since it is the smallest.
66 and 73 have an LCM of 4818.
Least Common Multiple of 66 and 73 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 66 and 73, than apply into the LCM equation.
GCF(66,73) = 1
LCM(66,73) = ( 66 × 73) / 1
LCM(66,73) = 4818 / 1
LCM(66,73) = 4818
