If you multiply all the prime factors you've found together and the result is the number, you have found all of them.
When each one of them is a prime.
not able to know what you mean?
Write the number in terms of its prime factors. So suppose is is:Z = ap*bq*cr ...where a, b, c are prime factors and p, q, r are indices.Then the total number of factors of Z is (p+1)*(q+1)*(r+1) ...If you have fewer, you have missed some out.Alternatively,Test Z for divisibility by each integer, from 1 upwards to sqrt(Z). At each stage, make a note of any factor found as well as the quotient when it divides Z.If you are thorough, you will find all the factors. This method may be simpler but relies absolutely on systematically going through many integers as potential divisors.
The numbers in a mulitplication question are called factors. The answer is a product. So, say if the question was 5x5. We all know it is 25. 5 and 5 are your factors, and 25 is your product.
i dont know you noob i dont know you noob
How to know that you found all the factors for example my teacher taught me that when u reach a double diget number that is all the factors. ( 6x6)-~ double diget number
When all the factors are prime.
All of the factors are prime.
All of the factors are prime.
When each one of them is a prime.
List them all, and multiply to see if you get the original number.
First to be able to find an abundant number you have find all the factors of any number. Then add them all up. If the total is bigger than the number you found out the factors of then it is an abundant number and if the total is less than the number you found out the factors for it is a deficiant number and finally if the total is the same number as the one you found out the factors for it is called a perfect number. Thanks for learning from me. I hope you have understood what i have typed. Bye!
i also really want to know the jacket if youve found it please could you tell me where to purchase it, if youve got skype my name is david.rothwell37 or please somehow inbox me or something on answers.com thanks :)
you'll know once youve got a cold or the sniffles
To know that a number is prime you need to know that it has no factors other than 1 and the number itself.To know that a number is composite you only need to know one factor other than the number itself or 1.
You don't.If you know just one factor, other than 1 and the number itself, you will know that the number is composite.A prime has only two factors: 1 and itself. So all the factors is no big deal.
Youve got to know alot of people! lol
