Least Common Multiple (LCM) of 45 and 53 with the help of Prime Factorisation
One method for determining the LCM of 45 and 53 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 45's prime factorization:
| 3 | 45 |
| 3 | 15 |
| 5 | 5 |
| 1 |
Prime factors of 45 are 3,5.
45 = 32×51
And this is 53's prime factorization:
| 53 | 53 |
| 1 |
Prime factors of 53 are 53.
53 = 531
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: 3,5,53
.32×51×531 = 2385
This shows that the LCM of 45 and 53 is 2385.
How to Calculate the LCM of 45 and 53 Using Common Multiples
The first step in determining the Least Common Multiple of 45 and 53 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 45 and 53:
Lets look at the first ten multiples of these numbers, 45 and 53:
45,90,135,180,225,270,315,360,405,765 are the first ten multiples of 45.
53,106,159,212,265,318,371,424,477,901 are the first ten multiples of 53.
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 45 and 53, for example, are 540, 765, and 848. 2385 is the least common multiple since it is the smallest.
45 and 53 have an LCM of 2385.
Least Common Multiple of 45 and 53 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 45 and 53, than apply into the LCM equation.
GCF(45,53) = 1
LCM(45,53) = ( 45 × 53) / 1
LCM(45,53) = 2385 / 1
LCM(45,53) = 2385
