The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.

Do the division, if there is no remainder, it is divisible. Seriously, many of the "divisibility rules" that have been discovered become more complicated than doing the actual division. For practical purposes, just learn the divisibility rules for a few simple cases (divisibility rules by 2, 4, 8, 5, 10, 3, 9, 7, 11, and 13), and for all other cases, just do the division.

fractions help you write out divisibility rules because divisibility rules help with fractions . Glad I would help good bye

The answer will depend on the divisibility rules list.

Since 1992 is divisible by 4, it is a leap year - meaning it has a February 29.(About divisibility by 4, special rules apply at the end of each century.)Since 1992 is divisible by 4, it is a leap year - meaning it has a February 29.(About divisibility by 4, special rules apply at the end of each century.)Since 1992 is divisible by 4, it is a leap year - meaning it has a February 29.(About divisibility by 4, special rules apply at the end of each century.)Since 1992 is divisible by 4, it is a leap year - meaning it has a February 29.(About divisibility by 4, special rules apply at the end of each century.)

The divisibility rules for a prime number is if it is ONLY divisible by 1, and itself.

use divisibility rules to find at least four factors of the number 19

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.

Factors are divisors. If you know the divisibility rules, you know that 80 is divisible by 1, 2, 4, 5 and 8. If you divide 80 by those numbers, you find the other half of the factor pairs.

Those for 1, 2, 4, 5 and 8.

i think divisibility rules help with fractions because it helps you reduce the fraction to make i a simple fraction.

It isn't worthwhile to invent or memorize complicated divisibility rules for lots of numbers. Just carrying out the divisions is faster in most cases.

Any multiple of two must end in 0, 2, 4, 6 or 8.

5364 is even because if you use your divisibility rules 4 is even so that mean 5364 is even.

For any practical purpose, it is easier to simply divide, instead of looking for fancy divisibility rules. However, you can apply the divisibility rules for 3 and for 7. This works because (a) their product is 21, and (b) these numbers are relatively prime.

If the last 4 digits are divisible by 80, the entire number is divisible by 80.But really, it is hardly worth-while to learn divisibility rules for a large amount of numbers; only for a few small numbers. Normally it is easier to just do the division.

Divisibility rules help you find the factors of a number. Once you've found the factors for two or more numbers, you can find what they have in common. Take 231 and 321. If you know the divisibility rules, you know that they are both divisible by 3, so 3 is a common factor.

If a number is divisible by 3, and also by 4, then it is divisible by 12 - so you might use the divisibility rules for those two numbers. Although it might be simpler just to perform the division.
