`217xx337=`______.

Answer

To solve the problem of multiplying 217 by 337, we will follow the standard multiplication method step by step.

### Step 1: Write the numbers in a column format
```
217
× 337
```

### Step 2: Multiply the bottom number's units place (7) with the top number (217)
- 7 × 7 = 49 (write down 9 and carry over 4)
- 7 × 1 = 7, plus the carry over 4 = 11 (write down 1 and carry over 1)
- 7 × 2 = 14, plus the carry over 1 = 15 (write down 15)

So, the first row of the product is:
```
217
× 337
-------
1519 (This is 217 × 7)
```

### Step 3: Multiply the bottom number's tens place (3) with the top number (217)
- 3 × 7 = 21 (write down 1 and carry over 2)
- 3 × 1 = 3, plus the carry over 2 = 5 (write down 5)
- 3 × 2 = 6 (write down 6)

Since this is the tens place, we need to add a zero at the end:
```
217
× 337
-------
1519
+ 6510 (This is 217 × 30)
```

### Step 4: Multiply the bottom number's hundreds place (3) with the top number (217)
- 3 × 7 = 21 (write down 1 and carry over 2)
- 3 × 1 = 3, plus the carry over 2 = 5 (write down 5)
- 3 × 2 = 6 (write down 6)

Since this is the hundreds place, we need to add two zeros at the end:
```
217
× 337
-------
1519
+ 6510
+65100 (This is 217 × 300)
```

### Step 5: Add all the rows together
```
1519
+ 6510
+65100
-------
73129
```

Thus, the final answer for 217 multiplied by 337 is **73129**.

### Final Answer:
**73129**
