Multiples of 431 =431,862,1293,1724,2155,2586,3017,3448,3879,4310,4741,5172,5603,6034,6465,6896,7327,

Multiples of 436 =436,872,1308,1744,2180,2616,3052,3488,3924,4360,4796,5232,5668,6104,6540,6976,7412,

Now, get the least common multiple of 431, 436 which is 187916

So, the LCM of 431, 436 is 187916.

One method for determining the LCM of 431 and 436 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 431's prime factorization:

Prime factors of 431 are 431.

431 = 431¹

And this is 436's prime factorization:

Prime factors of 436 are 2,109.

436 = 2²×109¹

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:431, 2,109

2²×109¹×431¹ = 187916

This shows that the LCM of 431 and 436 is 187916.

The first step in determining the Least Common Multiple of 431 and 436 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 431 and 436:

Lets look at the first ten multiples of these numbers, 431 and 436:

431,862,1293,1724,2155,2586,3017,3448,3879,7327 are the first ten multiples of 431.

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

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 431 and 436, for example, are 5172, 7327, and 6976. 187916 is the least common multiple since it is the smallest.

431 and 436 have an LCM of 187916.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 431 and 436, than apply into the LCM equation.

GCF(431,436) = 1
LCM(431,436) = ( 431 × 436) / 1
LCM(431,436) = 187916 / 1
LCM(431,436) = 187916
