Homework Statement
Factorize ##587## in base ##11##
Relevant Equations
Knowledge of changing bases
I know and understand ##299 \times 2 = 587## in base ##11##.

But I don't know how to do the reverse operation. Meaning given ##587## in base ##11##, I would never be able to decipher that it can be broken into ##299\times 2##. In fact I wouldn't be able to produce one single factor because I don't understand the reverse operation.

In base ##10##, if I were to take the number ##300##, I can immediately see that ##300=3 \times 10 \times 10##, but if the base is different then I can't see nor understand.

Thanks for the help.

If you worked on base 11 all the time, you would start to remember various patterns. The best plan is to convert to and from base 10. Not least because you know the prime numbers in base 10. There are lists of them everywhere.

FAQ: Factorize a number in a different base

What does it mean to factorize a number in a different base?

Factorizing a number in a different base means expressing the number as a product of its prime factors, but interpreting and performing all calculations in a numeral system other than base 10 (decimal). For example, factorizing in base 2 (binary) or base 16 (hexadecimal).

How do you convert a number to a different base before factorizing?

To convert a number to a different base, you repeatedly divide the number by the new base and record the remainders. The remainders, read in reverse order, form the number in the new base. For example, to convert the decimal number 10 to binary, you would divide 10 by 2, yielding remainders of 0, 1, 0, and 1, which read as 1010 in binary.

Are the factors of a number the same in different bases?

The prime factors of a number remain the same regardless of the base used for the factorization process. However, the representation of these factors will differ according to the base. For instance, the prime factors of 10 (decimal) are 2 and 5, which in binary are represented as 10 and 101 respectively.

What are the challenges of factorizing numbers in non-decimal bases?

Challenges include understanding and performing arithmetic operations in the new base, correctly interpreting the representation of numbers, and ensuring accurate division and multiplication processes. Additionally, specialized algorithms may be required for efficient factorization in bases other than 10.

Are there any tools or software available to factorize numbers in different bases?

Yes, there are various tools and software available that can assist in factorizing numbers in different bases. These include online calculators, programming libraries, and mathematical software like MATLAB and Mathematica, which often have built-in functions for base conversion and factorization.
