Least Common Multiple (LCM) of 52 and 56 with the help of Prime Factorisation
One method for determining the LCM of 52 and 56 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 52's prime factorization:
| 2 | 52 |
| 2 | 26 |
| 13 | 13 |
| 1 |
Prime factors of 52 are 2,13.
52 = 22×131
And this is 56's prime factorization:
| 2 | 56 |
| 2 | 28 |
| 2 | 14 |
| 7 | 7 |
| 1 |
Prime factors of 56 are 2,7.
56 = 23×71
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: 2,13,7
.23×71×131 = 728
This shows that the LCM of 52 and 56 is 728.
How to Calculate the LCM of 52 and 56 Using Common Multiples
The first step in determining the Least Common Multiple of 52 and 56 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 52 and 56:
Lets look at the first ten multiples of these numbers, 52 and 56:
52,104,156,208,260,312,364,416,468,884 are the first ten multiples of 52.
56,112,168,224,280,336,392,448,504,952 are the first ten multiples of 56.
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 52 and 56, for example, are 624, 884, and 896. 728 is the least common multiple since it is the smallest.
52 and 56 have an LCM of 728.
Least Common Multiple of 52 and 56 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 52 and 56, than apply into the LCM equation.
GCF(52,56) = 4
LCM(52,56) = ( 52 × 56) / 4
LCM(52,56) = 2912 / 4
LCM(52,56) = 728
