GCF and LCM by Prime Factorization
... If the last two digits form a number divisible by 4, the number is also. If the last digit is a 5 or a 0, the number is divisible by 5. If the number is divisible by both 3 and 2, it is also divisible by 6. Take the last digit, double it, and subtract it from the rest of the number; if the answer is ...

Triangular Numbers
... The number used to describe each "triangle" is called a triangular number. Given a number, can you arrange that many dots into a triangle? If you can, you have identified a triangular number. The sequence of triangular numbers starts with 1, 3, 6, and so on. Draw a picture of the next triangle in th ...

... life. A less common way to represent a number is the so called Cantor expansion. Often presented as exercises in discrete math and computer science courses [8.2, 8.5], this system uses factorials rather than exponentials as the basis for the representation. It can be shown that the expansion is uniq ...
