Given Numbers are 47, 53

We can find the LCM of 47, 53 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 47 and 53

Multiples of 47 =47,94,141,188,235,282,329,376,423,470,517,564,611,658,705,752,799,

Multiples of 53 =53,106,159,212,265,318,371,424,477,530,583,636,689,742,795,848,901,

Now, get the least common multiple of 47, 53 which is 2491

So, the LCM of 47, 53 is 2491.

One method for determining the LCM of 47 and 53 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 47's prime factorization:

Prime factors of 47 are 47.

47 = 47¹

And this is 53's prime factorization:

Prime factors of 53 are 53.

53 = 53¹

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:47,53

47¹×53¹ = 2491

This shows that the LCM of 47 and 53 is 2491.

The first step in determining the Least Common Multiple of 47 and 53 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 47 and 53:

Lets look at the first ten multiples of these numbers, 47 and 53:

47,94,141,188,235,282,329,376,423,799 are the first ten multiples of 47.

53,106,159,212,265,318,371,424,477,901 are the first ten multiples of 53.

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 47 and 53, for example, are 564, 799, and 848. 2491 is the least common multiple since it is the smallest.

47 and 53 have an LCM of 2491.

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 47 and 53, than apply into the LCM equation.

GCF(47,53) = 1
LCM(47,53) = ( 47 × 53) / 1
LCM(47,53) = 2491 / 1
LCM(47,53) = 2491
