One method for determining the LCM of 140 and 146 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 140's prime factorization:2 | 140 |
2 | 70 |
5 | 35 |
7 | 7 |
1 |
Prime factors of 140 are 2, 5,7.
140 = 22×51×71
And this is 146's prime factorization:
2 | 146 |
73 | 73 |
1 |
Prime factors of 146 are 2,73.
146 = 21×731
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, 5,7,73
.22×51×71×731 = 10220
This shows that the LCM of 140 and 146 is 10220.
The first step in determining the Least Common Multiple of 140 and 146 is to generate a list of multiples for each number.
Lets look at the multiples of these two numbers, 140 and 146:
Lets look at the first ten multiples of these numbers, 140 and 146:
140,280,420,560,700,840,980,1120,1260,2380 are the first ten multiples of 140.
146,292,438,584,730,876,1022,1168,1314,2482 are the first ten multiples of 146.
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 140 and 146, for example, are 1680, 2380, and 2336. 10220 is the least common multiple since it is the smallest.
140 and 146 have an LCM of 10220.
The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 140 and 146, than apply into the LCM equation.
GCF(140,146) = 2
LCM(140,146) = ( 140 × 146) / 2
LCM(140,146) = 20440 / 2
LCM(140,146) = 10220
