One method for determining the LCM of 245 and 250 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 245's prime factorization:5 | 245 |
7 | 49 |
7 | 7 |
1 |
Prime factors of 245 are 5,7.
245 = 51×72
And this is 250's prime factorization:
2 | 250 |
5 | 125 |
5 | 25 |
5 | 5 |
1 |
Prime factors of 250 are 2,5.
250 = 21×53
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: 5,7,2
.21×53×72 = 12250
This shows that the LCM of 245 and 250 is 12250.
The first step in determining the Least Common Multiple of 245 and 250 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 245 and 250:
Lets look at the first ten multiples of these numbers, 245 and 250:
245,490,735,980,1225,1470,1715,1960,2205,4165 are the first ten multiples of 245.
250,500,750,1000,1250,1500,1750,2000,2250,4250 are the first ten multiples of 250.
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 245 and 250, for example, are 2940, 4165, and 4000. 12250 is the least common multiple since it is the smallest.
245 and 250 have an LCM of 12250.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 245 and 250, than apply into the LCM equation.
GCF(245,250) = 5
LCM(245,250) = ( 245 × 250) / 5
LCM(245,250) = 61250 / 5
LCM(245,250) = 12250
