    What is the cube root of 247?

    Answer

    ∛247 ≈
    6.2743

    Real cube root: the only number whose cube is 247.

    ≈ — rounded to 4 decimal places. 247 is not the cube of a rational number, so ∛247 is irrational: its decimal expansion never ends and never repeats.

    Prime factors
    247 = 13 × 19
    Take out of the root
    No prime appears three times, so ∛247 is already in simplest form.
    Between cubes
    6³ = 216 < 247 < 343 = 7³, so 6 < ∛247 < 7 and ∛247 ≈ 6.2743

    FAQ

    What is the cube root of 247?

    ∛247 ≈ 6.2743

    Can ∛247 be simplified?

    No: no prime appears three times in 247, so its only cube factor is 1 and ∛247 is already in simplest form. Since 6³ = 216 < 247 < 343 = 7³, ∛247 lies between 6 and 7: ∛247 ≈ 6.2743.

    Is ∛247 a rational number?

    No: 247 is not the cube of a rational number, and the cube root of a fraction p/q in lowest terms is rational only when p and q are both cubes. So ∛247 is irrational; its decimal never ends and never repeats: ∛247 ≈ 6.2743.
