So, the LCM of 436, 440 is 47960.

One method for determining the LCM of 436 and 440 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 436's prime factorization:

Prime factors of 436 are 2,109.

436 = 2²×109¹

And this is 440's prime factorization:

Prime factors of 440 are 2, 5,11.

440 = 2³×5¹×11¹

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: 2,109, 5,11

2³×5¹×11¹×109¹ = 47960

This shows that the LCM of 436 and 440 is 47960.

The first step in determining the Least Common Multiple of 436 and 440 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 436 and 440:

Lets look at the first ten multiples of these numbers, 436 and 440:

436,872,1308,1744,2180,2616,3052,3488,3924,7412 are the first ten multiples of 436.

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

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 436 and 440, for example, are 5232, 7412, and 7040. 47960 is the least common multiple since it is the smallest.

436 and 440 have an LCM of 47960.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 436 and 440, than apply into the LCM equation.

GCF(436,440) = 4
LCM(436,440) = ( 436 × 440) / 4
LCM(436,440) = 191840 / 4
LCM(436,440) = 47960
