What is LCM of 71 and 79

Given Numbers are 71, 79

We can find the LCM of 71, 79 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 71 and 79

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

Multiples of 79 =79,158,237,316,395,474,553,632,711,790,869,948,1027,1106,1185,1264,1343,

Now, get the least common multiple of 71, 79 which is 5609

So, the LCM of 71, 79 is 5609.

Least Common Multiple (LCM) of 71 and 79 with the help of Prime Factorisation

One method for determining the LCM of 71 and 79 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 71's prime factorization:


71 71
1

Prime factors of 71 are 71.

71 = 711

And this is 79's prime factorization:


79 79
1

Prime factors of 79 are 79.

79 = 791

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:71,79

.

711×791 = 5609

This shows that the LCM of 71 and 79 is 5609.

How to Calculate the LCM of 71 and 79 Using Common Multiples

The first step in determining the Least Common Multiple of 71 and 79 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 71 and 79:

Lets look at the first ten multiples of these numbers, 71 and 79:

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

79,158,237,316,395,474,553,632,711,1343 are the first ten multiples of 79.

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 71 and 79, for example, are 852, 1207, and 1264. 5609 is the least common multiple since it is the smallest.

71 and 79 have an LCM of 5609.

Least Common Multiple of 71 and 79 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 71 and 79, than apply into the LCM equation.

GCF(71,79) = 1
LCM(71,79) = ( 71 × 79) / 1
LCM(71,79) = 5609 / 1
LCM(71,79) = 5609
