345 in Binary

Decimal 345 in binary conversion provides the detailed information on what is the binary equivalent of (345)10, and the step-by-step work for how to convert the decimal (base-10) number 345 to its binary (base-2) equivalent.

(345)10 in binary is equal to:
(345)₁₀ = (?)₂
Perform successive MOD-2 operation for decimal 345, and mark the initial remainder as LSB and the final remainder as MSB as like the below.

345 MOD-2	345 / 2 = 172	Remainder is 1 → LSB
172 MOD-2	172 / 2 = 86	Remainder is 0
86 MOD-2	86 / 2 = 43	Remainder is 0
43 MOD-2	43 / 2 = 21	Remainder is 1
21 MOD-2	21 / 2 = 10	Remainder is 1
10 MOD-2	10 / 2 = 5	Remainder is 0
5 MOD-2	5 / 2 = 2	Remainder is 1
2 MOD-2	2 / 2 = 1	Remainder is 0
1 MOD-2	1 / 2 = 0	Remainder is 1 → MSB

Arrange the remainders from MSB to LSB forms the binary equivalent of 345.
345₁₀ = 101011001₂

Hence,
345 in binary is 101011001

where,
345₁₀ is the given decimal number,
10 in 345₁₀ represents the base-10 or decimal number system,
101011001₂ is the binary equivalent of the decimal 41,
2 in 101011001₂ represents the base-2 or binary number system.

Important Notes: (345)10 in Binary
The below are some of the important notes to be remembered while converting the base-10 number 345 into a binary number.

1. The initial or first remainder while performing MOD-2 operation for 345 is a Least Significant Bit (LSB).
2. The last remainder while performing MOD-2 operation for 345 is a Most Significant Bit (MSB).
3. The remainders of MOD-2 operation for 345 should be written from MSB to LSB to form the binary equivalent for the given decimal number (345)10.
