Divisibility Rules
Before we dive into the numbers, let’s quickly recap some basic rules of divisibility. These rules will help us determine if a number is divisible by 23 or not.
- Divisible by 2: Any number that ends in 0, 2, 4, 6, or 8 is divisible by 2.
- Divisible by 3: A number is divisible by 3 if the sum of its digits is divisible by 3.
- Divisible by 5: Numbers ending in 0 or 5 are divisible by 5.
- Divisible by 23: To check for divisibility by 23, we’ll need to perform some calculations.
The Magic of 23
The number 23 has some interesting properties. It’s a prime number, which means it has only two distinct positive divisors: 1 and 23. This characteristic simplifies our task. We need to find multiples of 23 within the range of 1 to 500.
How Many numbers up to 500 are divisible by 23
Calculating how many numbers up to 500 are divisible by 23 is a straightforward task. We’ll divide 500 by 23 and see how many times it goes evenly.
500 รท 23 = 21.74 (approximately)
So, 23 goes into 500 approximately 21 times without leaving a remainder. That means there are 21 numbers up to 500 that are divisible by 23.
