What is LCM of 84 and 88

Given Numbers are 84, 88

We can find the LCM of 84, 88 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 84 and 88

Multiples of 84 =84,168,252,336,420,504,588,672,756,840,924,1008,1092,1176,1260,1344,1428,

Multiples of 88 =88,176,264,352,440,528,616,704,792,880,968,1056,1144,1232,1320,1408,1496,

Now, get the least common multiple of 84, 88 which is 1848

So, the LCM of 84, 88 is 1848.

Least Common Multiple (LCM) of 84 and 88 with the help of Prime Factorisation

One method for determining the LCM of 84 and 88 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 84's prime factorization:


2 84
2 42
3 21
7 7
1

Prime factors of 84 are 2, 3,7.

84 = 22×31×71

And this is 88's prime factorization:


2 88
2 44
2 22
11 11
1

Prime factors of 88 are 2,11.

88 = 23×111

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, 3,7,11

.

23×31×71×111 = 1848

This shows that the LCM of 84 and 88 is 1848.

How to Calculate the LCM of 84 and 88 Using Common Multiples

The first step in determining the Least Common Multiple of 84 and 88 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 84 and 88:

Lets look at the first ten multiples of these numbers, 84 and 88:

84,168,252,336,420,504,588,672,756,1428 are the first ten multiples of 84.

88,176,264,352,440,528,616,704,792,1496 are the first ten multiples of 88.

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 84 and 88, for example, are 1008, 1428, and 1408. 1848 is the least common multiple since it is the smallest.

84 and 88 have an LCM of 1848.

Least Common Multiple of 84 and 88 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 84 and 88, than apply into the LCM equation.

GCF(84,88) = 4
LCM(84,88) = ( 84 × 88) / 4
LCM(84,88) = 7392 / 4
LCM(84,88) = 1848
