Problem: Find all factor pairs of 64.
Gemini-1.5 Flash:
Here's how to find all the factor pairs of 64: * **Start with 1:** 1 is a factor of every number, and its pair is the number itself (64). So our first pair is (1, 64). * **Check divisibility by 2:** 64 is even, so 2 is a factor. 64 / 2 = 32, so our next pair is (2, 32). * **Check divisibility by 4:** 64 is divisible by 4. 64 / 4 = 16, giving us (4, 16). * **Check divisibility by 8:** 64 is divisible by 8. 64 / 8 = 8, giving us (8, 8). Notice that we've reached the same number for both factors. * **We're done!** We don't need to check any larger numbers since we've already found all the pairs. **Here are all the factor pairs of 64:** (1, 64) (2, 32) (4, 16) (8, 8)

Problem: Find all factor pairs of 28.
Gemini-1.5 Flash:
Here's how to find all the factor pairs of 28: **Understanding Factors** Factors are numbers that divide evenly into another number. A factor pair is a set of two numbers that multiply to give you the original number. **Finding the Factor Pairs** 1. **Start with 1:** 1 is always a factor of any number. The pair with 1 is 28 (1 x 28 = 28). 2. **Check divisibility by 2:** 28 is even, so 2 is a factor. The pair with 2 is 14 (2 x 14 = 28). 3. **Continue checking:** - 3 does not divide evenly into 28. - 4 does divide evenly into 28. The pair with 4 is 7 (4 x 7 = 28). 4. **You've reached the middle:** Once you reach a factor that is greater than or equal to the other factor in the pair, you've found all the factor pairs. **The Factor Pairs of 28:** * 1 and 28 * 2 and 14 * 4 and 7
Expected answer: [(1, 28), (2, 14), (4, 7)]

Here's how to find the factor pairs of 91: * **Start with 1:** 1 is a factor of every number, and its pair is the number itself (91). So, one factor pair is (1, 91). * **Check divisibility by small primes:** * 91 is not divisible by 2 (it's odd). * 91 is not divisible by 3 (the sum of the digits, 1+9+1 = 11, is not divisible by 3). * 91 is divisible by 7 (91 / 7 = 13). * **The pair:** Since 7 is a factor, its pair is 13. **Therefore, the factor pairs of 91 are (1, 91) and (7, 13).**
Expected answer: [(1, 91), (7, 13)]

Problem: Find all factor pairs of 64.
Gemini-1.5 Flash:
Here's how to find all the factor pairs of 64: **Understanding Factors** Factors are numbers that divide evenly into another number. **Finding the Pairs** 1. **Start with 1:** 1 is a factor of every number. Since 64 / 1 = 64, our first factor pair is (1, 64). 2. **Move to the next number:** Try 2. 64 / 2 = 32, so our next factor pair is (2, 32). 3. **Continue:** Keep trying numbers, dividing 64 by them. If the result is a whole number, you've found another factor pair. * 64 / 4 = 16 -> (4, 16) * 64 / 8 = 8 -> (8, 8) **Important Note:** Notice that when we get to 8, the factors start repeating (we already have 8 and 8). This is a signal that we've found all the factor pairs. **List of Factor Pairs of 64** * (1, 64) * (2, 32) * (4, 16) * (8, 8)

Problem: Calculate all the factor pairs for the number 96.
Gemini-1.5 Flash:
Here's how to find all the factor pairs for 96: * **Start with 1:** 1 is a factor of every number, so the first pair is (1, 96). * **Check divisibility by 2:** 96 is even, so 2 is a factor. 96/2 = 48, so the next pair is (2, 48). * **Continue with other numbers:** Keep checking numbers to see if they divide evenly into 96. * 3 divides evenly into 96 (96/3 = 32), so we have (3, 32). * 4 divides evenly into 96 (96/4 = 24), so we have (4, 24). * 6 divides evenly into 96 (96/6 = 16), so we have (6, 16). * 8 divides evenly into 96 (96/8 = 12), so we have (8, 12). Notice that as we keep checking, the factors we're finding are getting closer together. We've now reached a point where the next number we would check (9) is larger than the factors we've already found.
