Are you asking what the divisibility rule for 4 is?
===========
A number is divisible by 5 if it ends in a 0 or a 5
=====
There are two ways to test for divisibility by 4.
A number is divisible by 4 if it is divisible by 2 twice. That is, the factor you get when you factor a 2 out must also be divisible by 2.
Example... is 516 divisible by 4?
Well, is it divisible by 2? Yes, it is even. Factor that 2 out you get 258. Is 258 also divisible by 2? Yes, it too is even. Since it was divisible by 2 and the quotient was also divisible by 2 then the original was divisible by 4.
But, 4's have another rule that is simpler.
All you have to do is look at the smallest two digits: the ones and tens place. You can ignore anything in the hundreds place or up. If the ones and tens place form a number that is divisible by 4 then the whole number is also divisible by 4
Example: Is 52848474116 divisible by 4?
Just take the last two digits off and test them. 16. Is 16 divisible by 4? Yes, so that whole mess of a number is also.

Do all even numbers are factors of all even numbers?
No. 4 is not a factor of 6. Also, 6 is not a factor of 4.
Which of these numbers have 2 as a factor?
All even numbers greater than 0 have 2 as a factor.
Why do all numbers have common factors?
Because 1 is a factor of all non-zero numbers.
A factor of all number?
Only the number 1 is a factor of all other integers.
Why does a factor of 0 make multiplication easy?
Because all numbers multiplied by zero give zero as a result ....
What are numbers that have no common factors?
Since one is a factor of all non-zero integers, all numbers have common factors.
What is the number that can be divided by all prime numbers and has no repeated factor?
There is no such number. Since there are infinitely many prime numbers, the only number that can be divided by all of them is zero. But that can also be divided by numbers with repeated factors.
What are the whole numbers?
The whole numbers are all numbers zero and up (including zero ).
What is a common factor that every number has?
1 is the factor that is common to all numbers.
What is the factor of all numbers?
One is a factor of all nonzero numbers.
Do all numbers with 12 as a factor have 2 and 10 as factors?
All numbers with 12 as a factor have 2 as a factor, but not all have 10 as a factor.
Do all even numbers have two as a factor?
Yes. All even numbers have 2 as a factor.
What are non-zero real numbers?
Non-Zero Real Numbers are infact complex conjugate numbers. They are negative prime numbers.
If a zero is placed behind a number is it even or odd?
Placing a zero to the right of a number multiplies it by a factor of 10, and all multiples of 10 are even numbers.(10 = 2 x 5).
