Introduction

In mathematics, converting numbers from one base to another is an essential skill that helps us understand the representation of numbers in different number systems. In this article, we will focus on converting the decimal number $1456_{10}$ to base 4. We will provide the answer in both lower and higher bases, making it easier for readers to understand the concept.

What is Base 4?

Base 4 is a number system that uses four distinct symbols or digits to represent numbers. The four digits used in base 4 are 0, 1, 2, and 3. In base 4, each digit position represents a power of 4, starting from the rightmost digit, which represents $4^0$ , then $4^1$ , $4^2$ , and so on.

Converting Decimal to Base 4

To convert a decimal number to base 4, we need to divide the decimal number by 4 and keep track of the remainders. The remainders will form the digits of the base 4 number, starting from the rightmost digit.

Step 1: Divide the Decimal Number by 4

We start by dividing the decimal number $1456_{10}$ by 4.

$1456 \div 4 = 364$ with a remainder of 0.

Step 2: Divide the Quotient by 4

Next, we divide the quotient 364 by 4.

$364 \div 4 = 91$ with a remainder of 0.

Step 3: Divide the Quotient by 4

We continue by dividing the quotient 91 by 4.

$91 \div 4 = 22$ with a remainder of 3.

Step 4: Divide the Quotient by 4

Next, we divide the quotient 22 by 4.

$22 \div 4 = 5$ with a remainder of 2.

Step 5: Divide the Quotient by 4

We continue by dividing the quotient 5 by 4.

$5 \div 4 = 1$ with a remainder of 1.

Step 6: Divide the Quotient by 4

Next, we divide the quotient 1 by 4.

$1 \div 4 = 0$ with a remainder of 1.

Step 7: Write the Remainders in Reverse Order

Now that we have the remainders, we write them in reverse order to get the base 4 representation of the decimal number $1456_{10}$ .

The base 4 representation of $1456_{10}$ is $21100_4$ .

Higher Base Representation

To represent the base 4 number $21100_4$ in higher bases, we can convert it to base 8 (octal) and base 16 (hexadecimal).

Base 8 (Octal) Representation

To convert the base 4 number $21100_4$ to base 8, we need to divide the base 4 number by 8 and keep track of the remainders.

$21100_4 \div 8 = 5260_4$ with a remainder of 4.

$5260_4 \div 8 = 1301_4$ with a remainder of 4.

$1301_4 \div 8 = 321_4$ with a remainder of 1.

$321_4 \div 8 = 80_4$ with a remainder of 1.

$80_4 \div 8 = 20_4$ with a remainder of 0.

$20_4 \div 8 = 2_4$ with a remainder of 4.

$2_4 \div 8 = 0_4$ with a remainder of 2.

The base 8 representation of $21100_4$ is $24411410_8$ .

Base 16 (Hexadecimal) Representation

To convert the base 4 number $21100_4$ to base 16, we need to divide the base 4 number by 16 and keep track of the remainders.

$21100_4 \div 16 = 5260_4$ with a remainder of 4.

$5260_4 \div 16 = 1301_4$ with a remainder of 4.

$1301_4 \div 16 = 321_4$ with a remainder of 1.

$321_4 \div 16 = 80_4$ with a remainder of 1.

$80_4 \div 16 = 20_4$ with a remainder of 0.

$20_4 \div 16 = 2_4$ with a remainder of 0.

$2_4 \div 16 = 0_4$ with a remainder of 2.

The base 16 representation of $21100_4$ is $2A4$ .
