Write 77 as the product of its prime factors.

Sure, here are the steps to write 77 as the product of its prime factors:

1. First, we need to find the prime numbers that can divide 77. The prime numbers less than 77 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73.

2. Start from the smallest prime number, which is 2. Check if it can divide 77. It can't because 77 is an odd number.

3. Move to the next prime number, which is 3. Check if it can divide 77. It can't because 77 divided by 3 does not result in a whole number.

4. Continue this process until you find a prime number that can divide 77. The first prime number that can divide 77 is 7. So, divide 77 by 7. The result is 11, which is also a prime number.

5. Therefore, 77 can be written as the product of its prime factors 7 and 11.

So, 77 = 7 * 11.
