Solution - Long multiplication
Step-by-step explanation
1. Rewrite the numbers from top to bottom aligned to the right
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 3 | 1 | 6 | 1 | 9 | 0 | ||
| × | 4 | ||||||
2. Multiply the numbers using long multiplication method
Start by multiplying the ones digit (4) of the multiplier 4 by each digit of the multiplicand 316,190, from right to left.
Multiply the ones digit (4) of the multiplicator by the number in the ones place value:
4×0=0
Write 0 in the ones place.
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 3 | 1 | 6 | 1 | 9 | 0 | ||
| × | 4 | ||||||
| 0 |
Multiply the ones digit (4) of the multiplicator by the number in the tens place value:
4×9=36
Write 6 in the tens place.
Because the result is greater than 9, carry the 3 to the hundreds place.
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 3 | |||||||
| 3 | 1 | 6 | 1 | 9 | 0 | ||
| × | 4 | ||||||
| 6 | 0 |
Multiply the ones digit (4) of the multiplicator by the number in the hundreds place value and add the carried number (3):
4×1+3=7
Write 7 in the hundreds place.
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 3 | |||||||
| 3 | 1 | 6 | 1 | 9 | 0 | ||
| × | 4 | ||||||
| 7 | 6 | 0 |
Multiply the ones digit (4) of the multiplicator by the number in the thousands place value:
4×6=24
Write 4 in the thousands place.
Because the result is greater than 9, carry the 2 to the ten thousands place.
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 3 | ||||||
| 3 | 1 | 6 | 1 | 9 | 0 | ||
| × | 4 | ||||||
| 4 | 7 | 6 | 0 |
Multiply the ones digit (4) of the multiplicator by the number in the ten thousands place value and add the carried number (2):
4×1+2=6
Write 6 in the ten thousands place.
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 2 | 3 | ||||||
| 3 | 1 | 6 | 1 | 9 | 0 | ||
| × | 4 | ||||||
| 6 | 4 | 7 | 6 | 0 |
Multiply the ones digit (4) of the multiplicator by the number in the hundred thousands place value:
4×3=12
Write 2 in the hundred thousands place.
Because the result is greater than 9, carry the 1 to the millions place.
| Place value | millions | hundred thousands | ten thousands | thousands | hundreds | tens | ones |
| 1 | 2 | 3 | |||||
| 3 | 1 | 6 | 1 | 9 | 0 | ||
| × | 4 | ||||||
| 1 | 2 | 6 | 4 | 7 | 6 | 0 |
The solution is: 1,264,760
