Least Common Multiple (LCM) of 6981 and 6985 with the help of Prime Factorisation

One method for determining the LCM of 6981 and 6985 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 6981's prime factorization:


3 6981
13 2327
179 179
1

Prime factors of 6981 are 3, 13,179.

6981 = 31×131×1791

And this is 6985's prime factorization:


5 6985
11 1397
127 127
1

Prime factors of 6985 are 5, 11,127.

6985 = 51×111×1271

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: 3, 13,179, 5, 11,127

.

31×51×111×131×1271×1791 = 48762285
