1 Greatest Common Divisor Exponents Sections 1.2 & 1.3 Review of NumbersGreatest Common DivisorExponentsSections 1.2 & 1.3
2 Whole Previous Information Types of numbers Natural Integers Rational Irrational
3 PurposeIn later mathematics, you will want to work with numbers in simplest form.It is easier to work with small numbers rather than large numbers.
4 Prime FactorizationBreaking a number down into it’s combination of prime factorsTo start prime factorization, ask yourself…“Will 2 divide this number…,Will 3 divide this number…,Will 5 divide this number…”
19 Terminology Factor Prime number Composite number Prime Factorization Exponential FormGreatest Common DivisorExpanded FormSumDifferenceProductQuantityReciprocal
20 Conclusion Any two are more numbers have a Greatest Common Divisor (either 1 or some other Factor)To find the GCD use Prime Factorization(match factors using the smallest exponential value)Rules of Exponents
