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.

Which numbers from the divisibility rules list divide the number 1840?
The answer will depend on the divisibility rules list.
What are the divisibility rules to find at least four factors of the number 312?
use divisibility rules to find at least four factors of the number 19
What divisibility rules were combined to make the divisibility rule of 36?
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
What are the divisibility rules to the number 312?
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.
What divisibility rules can be used to find the factor pairs of 80?
Those for 1, 2, 4, 5 and 8.
Which numbers from the divisibility rules list divide the number 1840?
The answer will depend on the divisibility rules list.
What are the divisibility rules of all prime numbers?
The divisibility rules for a prime number is if it is ONLY divisible by 1, and itself.
What are reasons of using the disivility rules?
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.
What are the divisibility rules to find at least four factors of the number 312?

What number goes into all of the divisibility rules?
The number 0.
How many numbers can divided by that number?
divided by what number use your divisibility rules
What does it means to use the divisibility rules to find factor pairs for eighty?
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.
What divisibility rules were combined to make the divisibility rule of 36?
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.

What is divisibility rules for 15?
If a number is divisible by 3 and 5, it is divisible by 15.
How can knowing the divisibility rules help to determine if a number is prime or composite?
Knowing the divisibility rules will help you by being able to recognize if a number has factors (other than one and itself) which are covered by the rules. This will save actually having to start doing divisions.
