Step-by-Step: How to Find the Divisors of 3888

An efficient way to find divisors uses the complementary pair trick: check each integer i from 1 to √3888 ≈ 62.35. If i divides 3888, then both i and 3888/i are divisors.

1. 1 divides 3888 (3888 ÷ 1 = 3888) → pair (1, 3888)
2. 2 divides 3888 (3888 ÷ 2 = 1944) → pair (2, 1944)
3. 3 divides 3888 (3888 ÷ 3 = 1296) → pair (3, 1296)
4. 4 divides 3888 (3888 ÷ 4 = 972) → pair (4, 972)
5. 6 divides 3888 (3888 ÷ 6 = 648) → pair (6, 648)
6. 8 divides 3888 (3888 ÷ 8 = 486) → pair (8, 486)
7. 9 divides 3888 (3888 ÷ 9 = 432) → pair (9, 432)
8. 12 divides 3888 (3888 ÷ 12 = 324) → pair (12, 324)
9. 16 divides 3888 (3888 ÷ 16 = 243) → pair (16, 243)
10. 18 divides 3888 (3888 ÷ 18 = 216) → pair (18, 216)
11. 24 divides 3888 (3888 ÷ 24 = 162) → pair (24, 162)
12. 27 divides 3888 (3888 ÷ 27 = 144) → pair (27, 144)
13. 36 divides 3888 (3888 ÷ 36 = 108) → pair (36, 108)
14. 48 divides 3888 (3888 ÷ 48 = 81) → pair (48, 81)
15. 54 divides 3888 (3888 ÷ 54 = 72) → pair (54, 72)
16. Collect all unique values: {1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 81, 108, 144, 162, 216, 243, 324, 432, 486, 648, 972, 1296, 1944, 3888} — total 30 divisors.
17. Sum: 1 + 2 + 3 + 4 + 6 + 8 + 9 + 12 + 16 + 18 + 24 + 27 + 36 + 48 + 54 + 72 + 81 + 108 + 144 + 162 + 216 + 243 + 324 + 432 + 486 + 648 + 972 + 1296 + 1944 + 3888 = 11284.

What Is a Divisor?

A divisor (also called a factor) of a positive integer n is any positive integer d such that n ÷ d has no remainder. In other words, d divides n evenly.

Every positive integer n has at least two divisors: 1 and n itself (with 1 being the trivial case of having only itself). Numbers with exactly 2 divisors are prime; numbers with 3 or more divisors are composite.

Why use this calculator? Beyond just listing divisors, this tool computes the sum σ(n), the count τ(n), prime factorization, divisor pairs (useful for visual learners and factoring problems), and detects whether n is a prime, a perfect square, or a perfect number.
