What is LCM of 67 and 71

Given Numbers are 67, 71

We can find the LCM of 67, 71 using the brute force method, prime factorization method, or GCD method.

To use brute force method, list the multiples of 67 and 71

Multiples of 67 =67,134,201,268,335,402,469,536,603,670,737,804,871,938,1005,1072,1139,

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 67, 71 which is 4757

So, the LCM of 67, 71 is 4757.

Least Common Multiple (LCM) of 67 and 71 with the help of Prime Factorisation

One method for determining the LCM of 67 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 67's prime factorization:


67 67
1

Prime factors of 67 are 67.

67 = 671

And this is 71's prime factorization:


71 71
1

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:67,71

.

671×711 = 4757

This shows that the LCM of 67 and 71 is 4757.

How to Calculate the LCM of 67 and 71 Using Common Multiples

The first step in determining the Least Common Multiple of 67 and 71 is to generate a list of multiples for each number.

Lets look at the multiples of these two numbers, 67 and 71:

Lets look at the first ten multiples of these numbers, 67 and 71:

67,134,201,268,335,402,469,536,603,1139 are the first ten multiples of 67.

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 67 and 71, for example, are 804, 1139, and 1136. 4757 is the least common multiple since it is the smallest.

67 and 71 have an LCM of 4757.

Least Common Multiple of 67 and 71 with GCF Formula

The formula of LCM is LCM(a,b) = ( a × b) / GCF(a,b).
We need to calculate greatest common factor 67 and 71, than apply into the LCM equation.

GCF(67,71) = 1
LCM(67,71) = ( 67 × 71) / 1
LCM(67,71) = 4757 / 1
LCM(67,71) = 4757
