1- Any number is divisible by 1.
2- Any even number is divisible by 2.
3- If its digits add up to a number divisible by 3, the whole number is divisible by 3.
4- If the last two digits are divisible by 4, the whole number is divisible by 4.
5- If it ends in 5 or 0, the whole number is divisible by 5.
6- If it's even and also divisible by 3, the whole number is divisible by 6.
7- There is no rule for 7.
8- If the last three digits are divisible by 8, the whole number is divisible by 8.
9- If its digits add up to a number divisible by 9, the whole number is divisible by 9.
10- If it ends in 0, the whole number is divisible by 10.
divisibilty rules are how you times the number for instence if you want to find the divisibilty rule for 10 it would be the end number must be zero and then it would be a multiple of 10 and the divisibilty rule for 2 is the end number must be even then it would be a multiple of 2
i think divisibility rules help with fractions because it helps you reduce the fraction to make i a simple fraction.
3 and 9. And they divide into 123456789 whether or not you use divisibility rules!

Oh honey, divisibility rules have been around longer than your grandma's secret meatloaf recipe. But if you want a name to drop at your next trivia night, credit goes to good ol' Euclid. He's the OG mathematician who laid down the law on how numbers can play nice and divide evenly.
The divisibility rules for a prime number is if it is ONLY divisible by 1, and itself.

You can always check on the divisibility of a number by dividing it into another number. But if you know the divisibility rules, you can get that information easier and faster.

Divisibility rules have been developed and refined by mathematicians over the centuries. It is difficult to attribute the invention of divisibility rules to a specific individual. However, some early rules can be traced back to ancient civilizations like the Egyptians, Babylonians, and Greeks. These rules were further expanded upon and formalized by various mathematicians throughout history.
