Shooting for perfection
P.S. Thank you to Dreamy for help as well.
thanks so much. I am having trouble with understanding the method in slide 62, the one with the advanced method for finding the number of all possible
factors. can you explain it please? thanks!!
You may get better luck/success if you actually paste the contents or take a screenshot if it has formulas/other items that you can't easily copy.
yes of course, thank you.
Advanced method for finding the number of all possible
factors:
Write out each prime factor and their power, for
example, 12 can be written as follows:
2^2
3^1
5^0 etc (all other primes will have a zero power)
Add 1 to all powers and multiply them: (in this case 6)
and that’s the number of factors (1, 2, 3, 4, 6, 12)
Prime Factors of 462 = 2^1, 3^1, 7^1, 11^1
Total number of factors: 2x2x2x2 = 2^4= 16
