    What are the Factors of 1,600?

    Answer

    Factors of 1,600:
    21 factors: 1, 2, 4, 5, 8 … 400, 800, 1600
    all 21 factors

    1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 64, 80, 100, 160, 200, 320, 400, 800, 1600

    21 factors · 1600 = 26 × 52 · composite

    Underlined — prime: 2, 5 · 1 — neither prime nor composite · others — composite

    Factor pairs of 1,600

    • 1 × 1600
    • 2 × 800
    • 4 × 400
    • 5 × 320
    • 8 × 200
    • 10 × 160
    • 16 × 100
    • 20 × 80
    • 25 × 64
    • 32 × 50
    • 40 × 40

    40 × 40 is a pair of one factor — that is why 1600 has an odd number of factors, 21.

    1600 = 26 × 52 → (6 + 1) × (2 + 1) = 21 factors: add 1 to each exponent and multiply.
