Terminology | Definition |
prime number | A whole number greater than 1 whose only positive factors are 1 and itself. |
composite number | A whole number greater than 1 that has positive factors other than 1 and itself. |
prime factorization | Expressing a whole number as a product of prime numbers. |
factor tree | A diagram that can be used to write the prime factorization of a number. |
common factor | A whole number that is a factor of two or more nonzero whole numbers. |
GCF (Greatest Common Factor) | The greatest whole number that is a factor of two or more nonzero whole numbers. |
relatively prime | Two or more nonzero whole numbers whose greatest common factor is 1. |
simplest form | A fraction is in simplest form if its numerator and denominator have a greatest comon factor of 1. |
equivalent fractions | Fractions that represent the same part-to-whole relationship. Equivalent fractions have the same simpest form. |
multiple | A multiple of a number is the product of a the number and any nonzero whole number. |
common multiple | A multiple that is shared by two or more numbers. |
LCM (Least Common Multiple) | The least number that is a common multiple of two or more whole numbers. |
LCD (least common denominator) | The least common multiple of the denominators of two or more fractions. |
Scientific Notation | A number that is written in scientific notation if it has the from C * 10 to the Nth power, where c is greater than or equal to 1 and less than 10, and n is an integer... see book for an example if needed. |
Standard Form | An actual number with no exponents... i.e. 54,000 or .0000000456. |
