Multiples of 66 =66,132,198,264,330,396,462,528,594,660,726,792,858,924,990,1056,1122,
Multiples of 74 =74,148,222,296,370,444,518,592,666,740,814,888,962,1036,1110,1184,1258,
Now, get the least common multiple of 66, 74 which is 2442
So, the LCM of 66, 74 is 2442.
One method for determining the LCM of 66 and 74 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 74's prime factorization:
2 | 74 |
37 | 37 |
1 |
Prime factors of 74 are 2,37.
74 = 21×371
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, 3,11,37
.21×31×111×371 = 2442
This shows that the LCM of 66 and 74 is 2442.
The first step in determining the Least Common Multiple of 66 and 74 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 66 and 74:
Lets look at the first ten multiples of these numbers, 66 and 74:
66,132,198,264,330,396,462,528,594,1122 are the first ten multiples of 66.
74,148,222,296,370,444,518,592,666,1258 are the first ten multiples of 74.
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 74, for example, are 792, 1122, and 1184. 2442 is the least common multiple since it is the smallest.
66 and 74 have an LCM of 2442.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 66 and 74, than apply into the LCM equation.
GCF(66,74) = 2
LCM(66,74) = ( 66 × 74) / 2
LCM(66,74) = 4884 / 2
LCM(66,74) = 2442
