60 is one of 5 numbers that has 12 arrays.
Division arrays are typically done by dividing the total number of objects by the number of rows. These can come in the form of blocks or circles arranged in a specific number.

It's a prime number. Therefore the only rectangular array it has is 1*73 (or 73*1)

Think of the chairs as arrays. The dimensions of the arrays give you the factors of 18.

we can call the number that cannot be arranged into 2- row arrays multiple arrays.

You can only do multiplation so a whole number is divisble by another whole number when the quotient is a whole number and the remainder is 0

There are no smaller arrays. If the number of rows is smaller then the number of columns is larger and, conversely, if the number of columns is smaller then the number of rows is larger.
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!
If you answer 42x42,the answer is1 764 arrays.
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.
