Assigning each letter of the alphabet the numerical values of its position in the alphabet (a=1, b=2, c=3, etc) find a familiar first name witha product of letter values that is equal to 100,000.

To find a familiar first name with a product of letter values equal to 100,000, we need to assign numerical values to each letter of the alphabet.

Let's assign a=1, b=2, c=3, and so on, up to z=26.

We can now search for a name by calculating the product of the letter values for each letter in the name.

Here's how we can proceed:

1. Begin with a list of common first names in mind, like "John," "Sarah," or "Michael."
2. Take the first name on the list and assign numerical values to each letter of the name.
3. Calculate the product of these values by multiplying them together. For example, if we consider the name "John," the product would be (10 * 15 * 8 * 14 = 16,800).
4. Compare the product obtained with the target value of 100,000. If the product is lower, proceed to the next name on the list. If the product is higher, proceed to the next step.
5. Repeat steps 2-4 for each name on the list until you find a name with a product equal to 100,000.

Note: It is important to note that finding a familiar first name with a product of letter values equal to exactly 100,000 might be challenging since this would require finding a name with a unique combination of letter values.
