Given Numbers are 64, 71

We can find the LCM of 64, 71 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 64 and 71

Multiples of 64 =64,128,192,256,320,384,448,512,576,640,704,768,832,896,960,1024,1088,

Multiples of 71 =71,142,213,284,355,426,497,568,639,710,781,852,923,994,1065,1136,1207,

Now, get the least common multiple of 64, 71 which is 4544

So, the LCM of 64, 71 is 4544.

One method for determining the LCM of 64 and 71 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 64's prime factorization:

Prime factors of 64 are 2.

64 = 2⁶

And this is 71's prime factorization:

Prime factors of 71 are 71.

71 = 71¹

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:2,71

2⁶×71¹ = 4544

This shows that the LCM of 64 and 71 is 4544.

The first step in determining the Least Common Multiple of 64 and 71 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 64 and 71:

Lets look at the first ten multiples of these numbers, 64 and 71:

64,128,192,256,320,384,448,512,576,1088 are the first ten multiples of 64.

71,142,213,284,355,426,497,568,639,1207 are the first ten multiples of 71.

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 64 and 71, for example, are 768, 1088, and 1136. 4544 is the least common multiple since it is the smallest.

64 and 71 have an LCM of 4544.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 64 and 71, than apply into the LCM equation.

GCF(64,71) = 1
LCM(64,71) = ( 64 × 71) / 1
LCM(64,71) = 4544 / 1
LCM(64,71) = 4544
