What is 340 × 4?

Answer

340 × 4 =
1,360

340 × 4 and 4 × 340 are the same product — the order of the factors never changes the answer, only the working. Below, 340 is multiplied by 4 in a column, digit by digit.

340 × 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.

340 × 4 = 1,360

Step-by-Step Solution

Step 1: Multiply the multiplicand by the last digit of the multiplier, 4: 340 × 4 = 1,360.

  • 0 × 4 = 0. Write 0.
  • 4 × 4 = 16. Write 6 and carry 1.
  • 3 × 4 = 12, plus the carried 1 makes 13. Write 3 and carry 1.
  • No digits are left, so the carried 1 is written in front: the partial product is 1,360.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 1,360 ÷ 4 = 340 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.

340 × 4 is a number, not an area. If those are the sides of a room in feet, the answer is 1,360 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 340 × 4? (The answer is: 1,360). Enter the multiplicand (e.g. '340') and the multiplier (e.g. '4') and hit the button. The order of the two numbers does not matter — 340 × 4 and 4 × 340 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.
