Long Multiplication: 61 × 8
What is 61 × 8?
Answer
61 × 8 and 8 × 61 are the same product — the order of the factors never changes the answer, only the working. Below, 61 is multiplied by 8 in a column, digit by digit.
61 × 8 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.
| 6 | 1 | ||
| × | 8 | ||
| 4 | 8 | 8 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 8: 61 × 8 = 488.
- 1 × 8 = 8. Write 8.
- 6 × 8 = 48. Write 8 and carry 4.
- No digits are left, so the carried 4 is written in front: the partial product is 488.
61 × 8
=488
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 488 ÷ 8 = 61 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.
61 × 8 is a number, not an area. If those are the sides of a room in feet, the answer is 488 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
