To find 719 using the numbers \(1, 2, 4, 10, 50, 75\), you can employ basic arithmetic operations such as addition, subtraction, multiplication, and division. Here's one way to achieve it:

1. **Multiply 75 by 10** to get 750:
   \[
   75 \times 10 = 750
   \]

2. **Subtract 50** from 750:
   \[
   750 - 50 = 700
   \]

3. **Add 4** to 700:
   \[
   700 + 4 = 704
   \]

4. **Add 10** to 704:
   \[
   704 + 10 = 714
   \]

5. **Add 2** to 714:
   \[
   714 + 2 = 716
   \]

6. **Add 1** to 716:
   \[
   716 + 1 = 717
   \]

7. **Finally, add 2** to 717:
   \[
   717 + 2 = 719
   \]

So, \( 719 = (75 \times 10) - 50 + 4 + 10 + 2 + 1 + 2 \).
