    What is 720 × 7?

    Answer

    720 × 7 =
    5,040

    720 × 7 and 7 × 720 are the same product — the order of the factors never changes the answer, only the working. Below, 720 is multiplied by 7 in a column, digit by digit.

    720 × 7 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.

      720
    ×   7
     5040
    720 × 7 = 5,040

    Step-by-Step Solution

    Step 1: Multiply the multiplicand by the last digit of the multiplier, 7: 720 × 7 = 5,040.

    • 0 × 7 = 0. Write 0.
    • 2 × 7 = 14. Write 4 and carry 1.
    • 7 × 7 = 49, plus the carried 1 makes 50. Write 0 and carry 5.
    • No digits are left, so the carried 5 is written in front: the partial product is 5,040.

    720 × 7

    =

    5,040

    Check It, and What It Is Not

    Check by dividing back. Multiplication and division undo each other, so 5,040 ÷ 7 = 720 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.

    720 × 7 is a number, not an area. If those are the sides of a room in feet, the answer is 5,040 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 720 × 7? (The answer is: 5,040). Enter the multiplicand (e.g. '720') and the multiplier (e.g. '7') and hit the button. The order of the two numbers does not matter — 720 × 7 and 7 × 720 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.

    FAQ

    What is 720 × 7?

    720 × 7 = 5,040

    Is 720 × 7 the same as 7 × 720?

    Yes. Multiplication is commutative, so both come to 5,040. Only the working differs: this page multiplies by 7, which gives a single partial product.

    How do you check that 720 × 7 = 5,040?

    Divide the product back by one of the factors: 5,040 ÷ 7 = 720 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 720 × 7?
