Today I learned an easy way to do prime factors from my son. We were working on his homework. We’ll build a prime factor tree to accomplish this. I know a lot of you already know this stuff, but I don’t think I learned it in school, and if I did. I have forgotten it.<\/p>\n

In case you don’t know what a prime number is, it’s a number that can’t be divided into any other number and get a 0 remainder.<\/p>\n

I believe prime numbers up to 13 are.
\n0, 1, 2, 3, 5, 7, 9, 11, 13<\/p>\n

However we aren’t going to use the first 2 because 0 and 1 can be divided into anything. We’re trying to find the primes from 2 to 13.<\/p>\n

Pick a number any number any number.<\/p>\n

\r\n  80\r\n \/  \\\r\n8   10\r\n<\/pre>\n
8×10 = 80<\/p>\n
\r\n     80\r\n    \/  \\\r\n   8    \\\r\n  \/ \\    \\\r\n[2]   4   \\\r\n          10\r\n<\/pre>\n
2 x 4 = 8
\nWe’ve found our first prime which is 2.<\/p>\n
\r\n     80\r\n    \/  \\\r\n   8    \\\r\n  \/ \\    \\\r\n[2]   4   \\\r\n     \/ \\   \\\r\n   [2] [2] 10\r\n<\/pre>\n
We’ve now found our next prime numbers because 2 x 2 = 4
\nSo far our lowest prime numbers are 2 x 2 x 2 = 8 <\/p>\n
\r\n     80\r\n    \/  \\\r\n   8    \\\r\n  \/ \\    \\\r\n[2]   4   \\\r\n     \/ \\   \\\r\n   [2] [2] 10\r\n          \/  \\\r\n        [2]  [5]\r\n<\/pre>\n
We have now found our last 2 prime numbers 2 and 5.<\/p>\n
So in the end our prime factorization is: 2 x 2 x 2 x 2 x 5 = 80<\/p>\n
I’m so glad my son is teaching me math.  This is fun stuff.<\/p>\n","protected":false},"excerpt":{"rendered":"
