Long Multiplication: 490 × 5
What is 490 × 5?
Answer
490 × 5 and 5 × 490 are the same product — the order of the factors never changes the answer, only the working. Below, 490 is multiplied by 5 in a column, digit by digit.
490 × 5 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.

| 2 | 4 | 5 | 0 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 5: 490 × 5 = 2,450.
- 0 × 5 = 0. Write 0.
- 9 × 5 = 45. Write 5 and carry 4.
- 4 × 5 = 20, plus the carried 4 makes 24. Write 4 and carry 2.
- No digits are left, so the carried 2 is written in front: the partial product is 2,450.
490 × 5
=2,450
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 2,450 ÷ 5 = 490 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.
490 × 5 is a number, not an area. If those are the sides of a room in feet, the answer is 2,450 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
