Least Common Multiple (LCM) of 38 and 46 with the help of Prime Factorisation
One method for determining the LCM of 38 and 46 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 38's prime factorization:
| 2 | 38 |
| 19 | 19 |
| 1 |
Prime factors of 38 are 2,19.
38 = 21×191
And this is 46's prime factorization:
| 2 | 46 |
| 23 | 23 |
| 1 |
Prime factors of 46 are 2,23.
46 = 21×231
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: 2,19,23
.21×191×231 = 874
This shows that the LCM of 38 and 46 is 874.
How to Calculate the LCM of 38 and 46 Using Common Multiples
The first step in determining the Least Common Multiple of 38 and 46 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 38 and 46:
Lets look at the first ten multiples of these numbers, 38 and 46:
38,76,114,152,190,228,266,304,342,646 are the first ten multiples of 38.
46,92,138,184,230,276,322,368,414,782 are the first ten multiples of 46.
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 38 and 46, for example, are 456, 646, and 736. 874 is the least common multiple since it is the smallest.
38 and 46 have an LCM of 874.
Least Common Multiple of 38 and 46 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 38 and 46, than apply into the LCM equation.
GCF(38,46) = 2
LCM(38,46) = ( 38 × 46) / 2
LCM(38,46) = 1748 / 2
LCM(38,46) = 874
