So, the LCM of 455, 462 is 30030.

One method for determining the LCM of 455 and 462 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 455's prime factorization:

Prime factors of 455 are 5, 7,13.

455 = 5¹×7¹×13¹

And this is 462's prime factorization:

Prime factors of 462 are 2, 3, 7,11.

462 = 2¹×3¹×7¹×11¹

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: 5, 7,13, 2, 3,11

2¹×3¹×5¹×7¹×11¹×13¹ = 30030

This shows that the LCM of 455 and 462 is 30030.

The first step in determining the Least Common Multiple of 455 and 462 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 455 and 462:

Lets look at the first ten multiples of these numbers, 455 and 462:

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

462,924,1386,1848,2310,2772,3234,3696,4158,7854 are the first ten multiples of 462.

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 455 and 462, for example, are 5460, 7735, and 7392. 30030 is the least common multiple since it is the smallest.

455 and 462 have an LCM of 30030.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 455 and 462, than apply into the LCM equation.

GCF(455,462) = 7
LCM(455,462) = ( 455 × 462) / 7
LCM(455,462) = 210210 / 7
LCM(455,462) = 30030
