A rectangular number is a number which is the product of two consecutive integers.
1 is a non-rectangular number. The only factor of 1 is 1.
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!
Yes, 50 is a rectangular number because its factors can be arranged in rectanglar patterns 2 x 25 or 5 x 10.
Each factor pair is an array.
