    Factors & Primes Factors & Primes Presentation Transcript

    • Prime Factor Tree Discovering Prime Factors of Any Number
    • Definitions
      • Prime Number – An integer whose only factors are 1 and itself.
      • Factor – a number that can divide another number without a remainder.
      • Prime Factors – an expression of numbers that divides another integer without a remainder where all the factors are prime.
    • Let’s Choose a Number
      • Let’s use 36
      • Choose any 2 factors – let’s use 9 and 4
      • Now let’s factor these numbers, too
      • Next, arrange them from least to greatest
      • Last, re-write as exponents
      36 4 9 x 2 2 x x 3 3 2 2 x 3 2 2 2 3 3 x x
    • Let’s Try That Again!
      • Let’s use 36 again
      • Choose any 2 factors – let’s use 3 and 12
      • Now let’s factor these numbers, too
      • Oops, 6 is not prime - let’s factor again!
      • Next, arrange them from least to greatest
      • Last, re-write as exponents
      • Look, it’s the same answer!
      36 3 x x 2 6 12 3 x 3 x x 3 2 2 x 2 x 3 x x 2 3 2 2 x 3 2
    • Let’s Re-Cap
      • Composite numbers are made up of factors
      • In a Prime Factor Tree, the goal is to keep reducing each factor to its lowest possible prime factors
      • When you have all the prime factors identified, re-arrange them from least to greatest and re-write them as exponents
