Long Multiplication: 49 × 7
What is 49 × 7?
Answer
49 × 7 and 7 × 49 are the same product — the order of the factors never changes the answer, only the working. Below, 49 is multiplied by 7 in a column, digit by digit.
49 × 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.
| 4 | 9 | ||
| × | 7 | ||
| 3 | 4 | 3 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 7: 49 × 7 = 343.
- 9 × 7 = 63. Write 3 and carry 6.
- 4 × 7 = 28, plus the carried 6 makes 34. Write 4 and carry 3.
- No digits are left, so the carried 3 is written in front: the partial product is 343.
49 × 7
=343
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 343 ÷ 7 = 49 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.
49 × 7 is a number, not an area. If those are the sides of a room in feet, the answer is 343 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
