Convert 95876 into Base 13.

Solution:

The given number which is
95876 is written in Base 10. 95876 can also be written as 9587610. If you don't see any subscript at the given number, then that number is written in Base 10. Base 10 number is also called decimal system.  The digits of Base 10 number are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Base 10 number is a common number that we are using right now in everyday life.

On the other hand, Base 13 number is a number whose digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. Since 10, 11, and 12 are not accepted as a single digit, then we have to use a variable to substitute a two digit number. In this case, let A = 10, B = 11, and C = 12. Hence, the digits of Base 13 number are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, and C. If you see a subscript of 13 at the given number, then that number is written in Base 13. Base 13 number is also called tridecimal system.

Now, let's convert
95876 into Base 13. How? Let's divide 95876 by 13 as follows:

95876 ÷ 13 = 7375 + R(1)

Next, let's divide the quotient, which is 7375, as follows:

95876 ÷ 13 = 7375 + R(1)
7375 ÷ 13 =   567 + R(4)

Do the same thing with 567 until the quotient is 0 as follows:

95876 ÷ 13 = 7375 + R(1)
7375 ÷ 13 =   567 + R(4)

567 ÷ 13 =     43 + R(8)
43 ÷ 13 =       3 + R(4)
3 ÷ 13 =       0 + R(3)

The remainders will be the digits of Base 13 number. Use the digits of the remainders from bottom to top. Therefore,

95876
= 3484113
