discrete prepi

It is a branch of mathematics concerned with integers and their properties.

It means dividing a number evenly.

These are positive integers greater than 1 that cannot be divided by any number except themselves and 1.

• Composite Numbers

• Prime Numbers

These are positive integers that are greater than 1 and are not prime. It can be divided by

at least one (1) number (a factor) other than itself.

It is the largest non-zero integer d that is a common divisor of all the given integers

• Greatest Common Factor

• Least Common Multiple

It is the smallest integer that is a common multiple of all the given integers.

• Least Common Multiple

• Greatest Common Factor

A way of expressing a number as a product of its prime factors

• Divisibility

Let k be a positive integer greater than 1. Then if n is a positive integer, it can be expressed

uniquely in the form: n = amkm + am-1km-1 + … + a1k + a0

To convert from one number system to another, it is common practice to convert first to base 10.
