What is LCM of 30 and 35
Given Numbers are 30, 35
We can find the LCM of 30, 35 using the brute force method, prime factorization method, or GCD method.
To use brute force method, list the multiples of 30 and 35
Multiples of 30 =30,60,90,120,150,180,210,240,270,300,330,360,390,420,450,480,510,
Multiples of 35 =35,70,105,140,175,210,245,280,315,350,385,420,455,490,525,560,595,
Now, get the least common multiple of 30, 35 which is 210
So, the LCM of 30, 35 is 210.
Least Common Multiple (LCM) of 30 and 35 with the help of Prime Factorisation
One method for determining the LCM of 30 and 35 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 30's prime factorization:
| 2 | 30 |
| 3 | 15 |
| 5 | 5 |
| 1 |
Prime factors of 30 are 2, 3,5.
30 = 21×31×51
And this is 35's prime factorization:
| 5 | 35 |
| 7 | 7 |
| 1 |
Prime factors of 35 are 5,7.
35 = 51×71
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, 3,5,7
.21×31×51×71 = 210
This shows that the LCM of 30 and 35 is 210.
How to Calculate the LCM of 30 and 35 Using Common Multiples
The first step in determining the Least Common Multiple of 30 and 35 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 30 and 35:
Lets look at the first ten multiples of these numbers, 30 and 35:
30,60,90,120,150,180,210,240,270,510 are the first ten multiples of 30.
35,70,105,140,175,210,245,280,315,595 are the first ten multiples of 35.
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 30 and 35, for example, are 360, 510, and 560. 210 is the least common multiple since it is the smallest.
30 and 35 have an LCM of 210.
Least Common Multiple of 30 and 35 with GCF Formula
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 30 and 35, than apply into the LCM equation.
GCF(30,35) = 5
LCM(30,35) = ( 30 × 35) / 5
LCM(30,35) = 1050 / 5
LCM(30,35) = 210
