Given Numbers are 140, 148

We can find the LCM of 140, 148 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 140 and 148

Multiples of 140 =140,280,420,560,700,840,980,1120,1260,1400,1540,1680,1820,1960,2100,2240,2380,

Multiples of 148 =148,296,444,592,740,888,1036,1184,1332,1480,1628,1776,1924,2072,2220,2368,2516,

Now, get the least common multiple of 140, 148 which is 5180

So, the LCM of 140, 148 is 5180.

One method for determining the LCM of 140 and 148 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:

Prime factors of 140 are 2, 5,7.

140 = 2²×5¹×7¹

And this is 148's prime factorization:

Prime factors of 148 are 2,37.

148 = 2²×37¹

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, 5,7,37

2²×5¹×7¹×37¹ = 5180

This shows that the LCM of 140 and 148 is 5180.

The first step in determining the Least Common Multiple of 140 and 148 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 140 and 148:

Lets look at the first ten multiples of these numbers, 140 and 148:

140,280,420,560,700,840,980,1120,1260,2380 are the first ten multiples of 140.

148,296,444,592,740,888,1036,1184,1332,2516 are the first ten multiples of 148.

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 148, for example, are 1680, 2380, and 2368. 5180 is the least common multiple since it is the smallest.

140 and 148 have an LCM of 5180.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 140 and 148, than apply into the LCM equation.

GCF(140,148) = 4
LCM(140,148) = ( 140 × 148) / 4
LCM(140,148) = 20720 / 4
LCM(140,148) = 5180
