One method for determining the LCM of 453 and 457 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 453's prime factorization:

Prime factors of 453 are 3,151.

453 = 3¹×151¹

And this is 457's prime factorization:

Prime factors of 457 are 457.

457 = 457¹

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: 3,151,457

3¹×151¹×457¹ = 207021

This shows that the LCM of 453 and 457 is 207021.

The first step in determining the Least Common Multiple of 453 and 457 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 453 and 457:

Lets look at the first ten multiples of these numbers, 453 and 457:

453,906,1359,1812,2265,2718,3171,3624,4077,7701 are the first ten multiples of 453.

457,914,1371,1828,2285,2742,3199,3656,4113,7769 are the first ten multiples of 457.

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 453 and 457, for example, are 5436, 7701, and 7312. 207021 is the least common multiple since it is the smallest.

453 and 457 have an LCM of 207021.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 453 and 457, than apply into the LCM equation.

GCF(453,457) = 1
LCM(453,457) = ( 453 × 457) / 1
LCM(453,457) = 207021 / 1
LCM(453,457) = 207021
