What Makes 97 Special?
Ninety-seven is a unique number because it's a prime number. This means it can only be divided by two things: the number 1 and itself (97). Think of it like a building block that can't be broken down into smaller, equal parts using multiplication.
Understanding Prime Numbers
A prime number is a whole number greater than 1 that has only two factors (divisors): 1 and itself.
- For example, 7 is a prime number because you can only get 7 by doing 1 × 7.
- Numbers like 4 are not prime because you can get 4 by 1 × 4, but also by 2 × 2.
Prime numbers are super important in mathematics and even in computer security!
What is an Odd Number?
An odd number is any integer that cannot be divided exactly by 2. When you divide an odd number by 2, you will always have a remainder of 1.
- Numbers like 1, 3, 5, 7, and so on are all odd numbers.
- Ninety-seven fits this rule perfectly, as 97 divided by 2 is 48 with a remainder of 1.
