Given Numbers are 456, 460

We can find the LCM of 456, 460 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 456 and 460

Multiples of 456 =456,912,1368,1824,2280,2736,3192,3648,4104,4560,5016,5472,5928,6384,6840,7296,7752,

Multiples of 460 =460,920,1380,1840,2300,2760,3220,3680,4140,4600,5060,5520,5980,6440,6900,7360,7820,

Now, get the least common multiple of 456, 460 which is 52440

So, the LCM of 456, 460 is 52440.

One method for determining the LCM of 456 and 460 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 456's prime factorization:

Prime factors of 456 are 2, 3,19.

456 = 2³×3¹×19¹

And this is 460's prime factorization:

Prime factors of 460 are 2, 5,23.

460 = 2²×5¹×23¹

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, 3,19, 5,23

2³×3¹×5¹×19¹×23¹ = 52440

This shows that the LCM of 456 and 460 is 52440.

The first step in determining the Least Common Multiple of 456 and 460 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 456 and 460:

Lets look at the first ten multiples of these numbers, 456 and 460:

456,912,1368,1824,2280,2736,3192,3648,4104,7752 are the first ten multiples of 456.

460,920,1380,1840,2300,2760,3220,3680,4140,7820 are the first ten multiples of 460.

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 456 and 460, for example, are 5472, 7752, and 7360. 52440 is the least common multiple since it is the smallest.

456 and 460 have an LCM of 52440.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 456 and 460, than apply into the LCM equation.

GCF(456,460) = 4
LCM(456,460) = ( 456 × 460) / 4
LCM(456,460) = 209760 / 4
LCM(456,460) = 52440
