Work out product of n numbers instantly with clear inputs, formula shown and shareable results.
The product multiplies every value together. The geometric mean is the nth root of that product, which is the appropriate average for quantities that combine multiplicatively, such as growth rates.
Product
P = x₁ × x₂ × … × xₙ
Geometric mean
GM = P^(1/n)
210, with a geometric mean of 210^(1/4) ≈ 3.807307.
Multiplication by zero always gives zero, which is also why the geometric mean is undefined when any value is zero or negative.
