What is 68 × 4?

Answer

68 × 4 =
272

68 × 4 and 4 × 68 are the same product — the order of the factors never changes the answer, only the working. Below, 68 is multiplied by 4 in a column, digit by digit.

68 × 4 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, 4: 68 × 4 = 272.

  • 8 × 4 = 32. Write 2 and carry 3.
  • 6 × 4 = 24, plus the carried 3 makes 27. Write 7 and carry 2.
  • No digits are left, so the carried 2 is written in front: the partial product is 272.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 272 ÷ 4 = 68 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.

68 × 4 is a number, not an area. If those are the sides of a room in feet, the answer is 272 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 68 × 4? (The answer is: 272). Enter the multiplicand (e.g. '68') and the multiplier (e.g. '4') and hit the button. The order of the two numbers does not matter — 68 × 4 and 4 × 68 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.
