Given Numbers are 143, 151

We can find the LCM of 143, 151 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 143 and 151

Multiples of 143 =143,286,429,572,715,858,1001,1144,1287,1430,1573,1716,1859,2002,2145,2288,2431,

Multiples of 151 =151,302,453,604,755,906,1057,1208,1359,1510,1661,1812,1963,2114,2265,2416,2567,

Now, get the least common multiple of 143, 151 which is 21593

So, the LCM of 143, 151 is 21593.

One method for determining the LCM of 143 and 151 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 143's prime factorization:

Prime factors of 143 are 11,13.

143 = 11¹×13¹

And this is 151's prime factorization:

Prime factors of 151 are 151.

151 = 151¹

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: 11,13,151

11¹×13¹×151¹ = 21593

This shows that the LCM of 143 and 151 is 21593.

The first step in determining the Least Common Multiple of 143 and 151 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 143 and 151:

Lets look at the first ten multiples of these numbers, 143 and 151:

143,286,429,572,715,858,1001,1144,1287,2431 are the first ten multiples of 143.

151,302,453,604,755,906,1057,1208,1359,2567 are the first ten multiples of 151.

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 143 and 151, for example, are 1716, 2431, and 2416. 21593 is the least common multiple since it is the smallest.

143 and 151 have an LCM of 21593.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 143 and 151, than apply into the LCM equation.

GCF(143,151) = 1
LCM(143,151) = ( 143 × 151) / 1
LCM(143,151) = 21593 / 1
LCM(143,151) = 21593
