What is 72 × 6?

Answer

72 × 6 =
432

72 × 6 and 6 × 72 are the same product — the order of the factors never changes the answer, only the working. Below, 72 is multiplied by 6 in a column, digit by digit.

72 × 6 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, 6: 72 × 6 = 432.

  • 2 × 6 = 12. Write 2 and carry 1.
  • 7 × 6 = 42, plus the carried 1 makes 43. Write 3 and carry 4.
  • No digits are left, so the carried 4 is written in front: the partial product is 432.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 432 ÷ 6 = 72 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.

72 × 6 is a number, not an area. If those are the sides of a room in feet, the answer is 432 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.

Long Multiplication 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 72 × 6? (The answer is: 432). Enter the multiplicand (e.g. '72') and the multiplier (e.g. '6') and hit the button. The order of the two numbers does not matter — 72 × 6 and 6 × 72 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.
