So, the LCM of 440, 448 is 24640.

One method for determining the LCM of 440 and 448 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 440's prime factorization:

Prime factors of 440 are 2, 5,11.

440 = 2³×5¹×11¹

And this is 448's prime factorization:

Prime factors of 448 are 2,7.

448 = 2⁶×7¹

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, 5,11,7

2⁶×5¹×7¹×11¹ = 24640

This shows that the LCM of 440 and 448 is 24640.

The first step in determining the Least Common Multiple of 440 and 448 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 440 and 448:

Lets look at the first ten multiples of these numbers, 440 and 448:

440,880,1320,1760,2200,2640,3080,3520,3960,7480 are the first ten multiples of 440.

448,896,1344,1792,2240,2688,3136,3584,4032,7616 are the first ten multiples of 448.

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 440 and 448, for example, are 5280, 7480, and 7168. 24640 is the least common multiple since it is the smallest.

440 and 448 have an LCM of 24640.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 440 and 448, than apply into the LCM equation.

GCF(440,448) = 8
LCM(440,448) = ( 440 × 448) / 8
LCM(440,448) = 197120 / 8
LCM(440,448) = 24640
