Least Common Multiple (LCM) of 7031 and 7038 with the help of Prime Factorisation

One method for determining the LCM of 7031 and 7038 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 7031's prime factorization:


79 7031
89 89
1

Prime factors of 7031 are 79,89.

7031 = 791×891

And this is 7038's prime factorization:


2 7038
3 3519
3 1173
17 391
23 23
1

Prime factors of 7038 are 2, 3, 17,23.

7038 = 21×32×171×231

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: 79,89, 2, 3, 17,23

.

21×32×171×231×791×891 = 49484178

This shows that the LCM of 7031 and 7038 is 49484178.

How to Calculate the LCM of 7031 and 7038 Using Common Multiples
