You're welcome!
If you want to just go through any number's prime factorization,
divide by 2 when you can
if you can't, divide by 3
if you can't, divide by 5
if you can't, divide by 7
if you can't, divide by 11
and if you can't divide by other primes.
Or, if you see a number like \(120\), go straight for the common sense \(12\times 10\) so you can get right to the lower numbers! But going through the primes is good, too.
\(120=2\times 60\) Side note: 60 is easy, too...
\(120=2\times2\times30\)
\(120=2\times2\times2\times15\)
2 doesn't work.
\(120=2\times2\times2\times3\times5\)
All primes.
