What is 27 × 8?

Answer

27 × 8 = 216

27 × 8 and 8 × 27 are the same product — the order of the factors never changes the answer, only the working. Below, 27 is multiplied by 8 in a column, digit by digit.

27 × 8 in a Column

The multiplicand goes on top, the multiplier underneath, both aligned on the right. The multiplier has a single digit, so there is one partial product and the answer goes straight under the line.

Step-by-Step Solution

Step 1: Multiply the multiplicand by the last digit of the multiplier, 8: 27 × 8 = 216.

  • 7 × 8 = 56. Write 6 and carry 5.
  • 2 × 8 = 16, plus the carried 5 makes 21. Write 1 and carry 2.
  • No digits are left, so the carried 2 is written in front: the partial product is 216.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 216 ÷ 8 = 27 must come out exactly, with no remainder.

Fractions are a different calculation. Both factors here are whole numbers; for 2/3 or 2 3/4 use the fraction multiplication calculator, which multiplies numerators and denominators separately.

27 × 8 is a number, not an area. If those are the sides of a room in feet, the answer is 216 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.

About "Long Multiplication Calculator" Calculator

This calculator multiplies two whole numbers the way it is done on paper: digit by digit, carrying where the column overflows, then adding the partial products together. For example, it can help you find out what is 27 × 8? (The answer is: 216). Enter the multiplicand (e.g. '27') and the multiplier (e.g. '8') and hit the button. The order of the two numbers does not matter — 27 × 8 and 8 × 27 are the same product — so either number can go on top. Fractions and mixed numbers belong to the fraction multiplication calculator, and the reverse operation is long division.

Is 27 × 8 the same as 8 × 27?

Yes. Multiplication is commutative, so both come to 216. Only the working differs: this page multiplies by 8, which gives a single partial product.

How do you check that 27 × 8 = 216?

Divide the product back by one of the factors: 216 ÷ 8 = 27 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

What are the partial products of 27 × 8?

There is only one: the multiplier 8 has a single digit, so 27 × 8 = 216 is written straight under the line, with no addition step.
