Least Common Multiple (LCM) of 61 and 66 with the help of Prime Factorisation
One method for determining the LCM of 61 and 66 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 61's prime factorization:
| 61 | 61 |
| 1 |
Prime factors of 61 are 61.
61 = 611
And this is 66's prime factorization:
| 2 | 66 |
| 3 | 33 |
| 11 | 11 |
| 1 |
Prime factors of 66 are 2, 3,11.
66 = 21×31×111
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:61, 2, 3,11
.21×31×111×611 = 4026
This shows that the LCM of 61 and 66 is 4026.
How to Calculate the LCM of 61 and 66 Using Common Multiples
The first step in determining the Least Common Multiple of 61 and 66 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 61 and 66:
Lets look at the first ten multiples of these numbers, 61 and 66:
61,122,183,244,305,366,427,488,549,1037 are the first ten multiples of 61.
66,132,198,264,330,396,462,528,594,1122 are the first ten multiples of 66.
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 61 and 66, for example, are 732, 1037, and 1056. 4026 is the least common multiple since it is the smallest.
61 and 66 have an LCM of 4026.
Least Common Multiple of 61 and 66 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 61 and 66, than apply into the LCM equation.
GCF(61,66) = 1
LCM(61,66) = ( 61 × 66) / 1
LCM(61,66) = 4026 / 1
LCM(61,66) = 4026
