THe LCM of 123 and 243 is 9963

The first step in working out the least common multiple of two numbers is to express them as their prime factors. In this case 123 and 243 can be broken down as follows:

123 = 41x3

243 = 3x3x3x3x3

The next step is to identify and discard the duplicates of any common factors. In this case, both numbers have a 3 as a prime factor, so we can discard one of these. Take all the other prime factors (41, 3, 3, 3, 3 and 3) and multiply them together to get the LCM:

41x3x3x3x3x3=9963

What is the least Common Multiple of 243 and 405?

To find the least common multiple (LCM) of 243 and 405, we first need to find the prime factorization of each number. The prime factorization of 243 is 3^5, and the prime factorization of 405 is 3^4 * 5. To calculate the LCM, we take the highest power of each prime factor that appears in either number, which gives us 3^5 * 5 = 1215. Therefore, the least common multiple of 243 and 405 is 1215.


What is the least common factor of 81 and 243?

The factors of 81 are 1, 3, 9, 27, and 81. The factors of 243 are 1, 3, 9, 27, 81, and 243. The common factors of 81 and 243 are 1, 3, 9, 27, and 81. Therefore, the least common factor (the smallest common factor) is 1.


What are all common factors of 243?

There cannot be a common factor of just one number. To be common, there needs to be at least two numbers; howver, the factors of 243 are 1, 3, 9, 27, 81, and 243.

What are the factors and prime factors of 243?

243 is a composite number because it has factors other than 1 and itself. It is not a prime number.The 8 factors of 243 are 1,2,3,4,9,27,81, and 243.The factor pairs of 243 are 1 x 243, 3 x 81, and 9 x 27.The proper factors of 243 are 1, 3, 9, 27, and 81 or,if the definition you are using excludes 1, they are 3, 9, 27, and 81.The prime factors of 243 are 3, 3, 3, 3, and 3. Note: There is repetition of these factors, so if the prime factors are being listed instead of the prime factorization, usually only the distinct prime factors are listed.The distinct prime factor (listing each prime factor only once) of 243 is 3.The prime factorization of 243 is 3 x 3 x 3 x 3 x 3 or, in exponential form, is 35.NOTE: There cannot be common factors, a greatest common factor, or a least common multiple because "common" refers to factors or multiples that two or more numbers have in common.
