Factors are integers that multiply to create a product.
3 x 4 = 12
3 and 4 are factors of 12.
Divisibility refers to a number capable of being divided by another number without a remainder: 24 is divisible by 4.
The number of factors of a given number corresponds to the different ways that number can be expressed as a product of two integers, which represents the possible dimensions of rectangular arrays. For instance, if a number has six factors, it can be arranged into rectangular arrays of dimensions that multiply to that number, such as 1x6, 2x3, and 3x2. Each unique pair of factors gives a distinct arrangement, illustrating the relationship between factors and rectangular arrays. Thus, the total number of factors directly determines the number of unique rectangular configurations possible for that number.
Oh, dude, there are like a bazillion different arrays you can make with 18. Okay, maybe not a bazillion, but definitely a lot. You can have arrays like [1, 2, 3, 4, 5, 6], [18], [9, 9], or even [2, 9, 7]. The possibilities are endless... well, not really, but you get the point.
The last draw has no bearing on the next draw. Each draw is random.
12, 14, and 20 have an even number of factors. 4, 9, and 16 also have an even number of factors, but since they're perfect squares, two of the factors are the same number in each case, so each appears to have an odd number of factors.
Just one. Or, two if you count (1, p) and (p, 1) as being different.
The Number of factors, (That is the number of pairs, such as 2= 1x2, 2x1), is equal to the number of rectangular arrays which can be made for each composite number. As such, the number of factors in the number 9 is 3, (1,3,9), and the number of rectangular arrays is also three (1x9, 9x1,3x3). Hope this helps!
Each factor pair is an array.
Records are distinguished from arrays by the fact that their number of fields is typically fixed, each field has a name, and that each field may have a different type.
I assume you mean that you have a number of rows, and that not all rows have the same number of "cells". Yes, in Java a two-dimensional array is implemented as an array of arrays (each item in the top-level array is, in itself, an array); a 3-dimensional array is an array of arrays of arrays, etc.; and there is no rule stating that all secondary (etc.) arrays must have the same number of elements.
identify two composite numbers that each have 8 as a factor

When you activate the ability "draw a card for each creature you control," you draw a number of cards equal to the total number of creatures you control.
To calculate the number of arrays that can be made out of 20 elements, we need to consider the possible combinations. Each element can either be included or excluded in the array, resulting in 2 choices for each element. Therefore, the total number of arrays that can be formed is 2^20, which equals 1,048,576.
You can make arrays with any number of dimensions (depending on RAM limitations, of course). However, internally, a two-dimensional array (for example) is stored as an array of arrays; that is, each first-level array contains an array of the second level. Similarly with higher dimensions.

1. List all factors of number (including 1 and the number, list each factor only once even if it goes in multiple times) 2. Add up all the factors 3. If the sum is equal to twice the original number, then the original number is perfect, if not, it is not perfect.
