684 in Octal

Decimal 684 in octal conversion provides the detailed information on what is the octal equivalent of (684)10, and the step-by-step work for how to convert the decimal (base-10) number 684 to its octal (base-8) equivalent.

(684)10 in octal is equal to:
(684)10 = (?)8

Perform successive MOD-8 operation for decimal 684, and mark the initial remainder as LSB and the final remainder as MSB as like the below.

MOD-8 of 684	684 / 8 = 85	Remainder is 4 → LSB
MOD-8 of 85	85 / 8 = 10	Remainder is 5
MOD-8 of 10	10 / 8 = 1	Remainder is 2
MOD-8 of 1	1 / 8 = 0	Remainder is 1 → MSB

Arrange the remainders from MSB to LSB forms the octal equivalent of 684.
684₁₀ = 1254₈

Hence,
684 in octal is 1254

where,
684₁₀ is the given decimal number,
10 in 684₁₀ represents the base-10 or decimal number system,
1254₈ is the octal equivalent of the decimal 684,
8 in 1254₈ represents the base-8 or octal number system.

Important Notes: (684)10 in Octal
