what numbers i can use to make in exponents a prime factorization of 560

1 answer

To find the prime factorization of 560, we start by dividing it by the smallest prime numbers and continue dividing until we reach 1. Here's how you can do it:

  1. Divide by 2 (the smallest prime number):

    • \( 560 \div 2 = 280 \)
    • \( 280 \div 2 = 140 \)
    • \( 140 \div 2 = 70 \)
    • \( 70 \div 2 = 35 \)
  2. Now divide by 5 (the next smallest prime number):

    • \( 35 \div 5 = 7 \)
  3. Finally, 7 is also a prime number.

So, we have divided 560 down to the prime factors:

  • We divided by \(2\) three times, giving us \(2^3\).
  • We divided by \(5\) once, giving us \(5^1\).
  • We divided by \(7\) once, giving us \(7^1\).

Putting it all together, the prime factorization of \(560\) is:

\[ 560 = 2^3 \times 5^1 \times 7^1 \]
