157 in binary is 10011101. Unlike the decimal number system where we use the digits 0 to 9 to represent a number, in a binary system, we use only 2 digits that are 0 and 1 (bits). We have used 8 bits to represent 157 in binary. In this article, let us learn how to convert the decimal number 157 to binary.
How to Convert 157 in Binary?
Step 1: Divide 157 by 2. Use the integer quotient obtained in this step as the dividend for the next step. Repeat the process until the quotient becomes 0.
| Dividend | Remainder |
|---|---|
| 157/2 = 78 | 1 |
| 78/2 = 39 | 0 |
| 39/2 = 19 | 1 |
| 19/2 = 9 | 1 |
| 9/2 = 4 | 1 |
| 4/2 = 2 | 0 |
| 2/2 = 1 | 0 |
| 1/2 = 0 | 1 |
Step 2: Write the remainder from bottom to top i.e. in the reverse chronological order. This will give the binary equivalent of 157.
Therefore, the binary equivalent of decimal number 157 is 10011101.

FAQs on 157 in Binary
What is 157 in Binary?
157 in binary is 10011101. To find decimal to binary equivalent, divide 157 successively by 2 until the quotient becomes 0. The binary equivalent can be obtained by writing the remainder in each division step from the bottom to the top.
Find the Value of 2 × 157 in Binary Form.
We know that 157 in binary is 10011101 and 2 is 10. Using the binary multiplication rules (0 × 0 = 0; 0 × 1 = 0 ; 1 × 0 = 0 and 1 × 1 = 1), we can multiply 10011101 × 10 = 100111010 which is 314 in the decimal number system. [157 × 2 = 314]
What is the Binary Equivalent of 157 + 69?
157 in binary number system is 10011101 and 69 is 1000101. We can add the binary equivalent of 157 and 69 using binary addition rules [0 + 0 = 0, 0 + 1 = 1, 1 + 1 = 10 note that 1 is a carry over to the next bit]. Therefore, (10011101)₂ + (1000101)₂ = (11100010)₂ which is nothing but 226.
