One method for determining the LCM of 448 and 455 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 448's prime factorization:

Prime factors of 448 are 2,7.

448 = 2⁶×7¹

And this is 455's prime factorization:

Prime factors of 455 are 5, 7,13.

455 = 5¹×7¹×13¹

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: 2,7, 5,13

2⁶×5¹×7¹×13¹ = 29120

This shows that the LCM of 448 and 455 is 29120.

The first step in determining the Least Common Multiple of 448 and 455 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 448 and 455:

Lets look at the first ten multiples of these numbers, 448 and 455:

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

455,910,1365,1820,2275,2730,3185,3640,4095,7735 are the first ten multiples of 455.

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 448 and 455, for example, are 5376, 7616, and 7280. 29120 is the least common multiple since it is the smallest.

448 and 455 have an LCM of 29120.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 448 and 455, than apply into the LCM equation.

GCF(448,455) = 7
LCM(448,455) = ( 448 × 455) / 7
LCM(448,455) = 203840 / 7
LCM(448,455) = 29120
