Answer

To find the digit at the units place in the product \( 653 \times 308 \times 402 \times 413 \), we can follow these steps:

### Step 1: Identify the units digits of each number
- The units digit of \( 653 \) is \( 3 \).
- The units digit of \( 308 \) is \( 8 \).
- The units digit of \( 402 \) is \( 2 \).
- The units digit of \( 413 \) is \( 3 \).

### Step 2: Multiply the units digits together
Now we will multiply the units digits we found:
1. Multiply the first two units digits:
\[ 3 \times 8 = 24 \]
The units digit of \( 24 \) is \( 4 \).

2. Next, multiply the result with the next units digit:
\[ 4 \times 2 = 8 \]
The units digit of \( 8 \) is \( 8 \).

3. Finally, multiply this result with the last units digit:
\[ 8 \times 3 = 24 \]
The units digit of \( 24 \) is \( 4 \).

### Conclusion
The units digit in the product \( 653 \times 308 \times 402 \times 413 \) is \( 4 \).
