The factors branch out from the previous factors until all of the factors are prime numbers. greatest common factor (GCF)˜greatest common factor (GCF):ÖThe greatest number that is a factor of two or more numbers. ÖExample: The greatest common factor of 30, 60, and 15 is 15. monomialnmonomial:ÖA number, a variable, or a product of a number and one or more variables.ÖExamples: 3, y, 2x, 5xy^2. powerpower:ÖAn expression of the form x^n, read x to the nth power. ÖExample: 7^4 is 7 raised to the fourth power, or 7 7 7 7.  prime factorizationŠprime factorization:ÖExpressing a composite number as a product of its prime factors.ÖExample:ÖThe prime factorization of 63 is 3 3 7.   prime numberRprime number:ÖA whole number, greater than 1, whose only factors are 1 and itself.  scientific notationÖscientific notation:ÖA system of writing numbers using multiplication and powers of ten. A number of the form a 10^n, where 1 < a < 10 and n is an integer.ÖExamples:Ö95,700 = 9.57 10^4,Ö0.000024 = 2.4 10^(-5)  simplest form of a fraction†simplest form of a fraction:ÖA fraction is in simplest form when the greatest common factor of the numerator and the denominator is 1.   standard form1standard form:ÖNumbers written without exponents.
