This topic is locked. If you want to discuss this question please re-post it in the respective forum.

1)How do we factor a negative number?
for example -24 is: 2x2x2x3x(-1) ??

2)Is -3 a multiple of 3? Is -12 a multiple of 3? Is zero a multiple of 3 ?(since 0:3=0 which is an integer)

3)When looking for the divisors of a positive number we should look for negative numbers too? (if the question doesn't state oherwise). For example if the question is how many are the divisors of 12, we should anwser 6: (1,2,3,4,6,12) or the correct answer is 12? (-1,-2,-3,-4,-6,
-12,1,2,3,4,6,12).

thanks everybody!

I saw a problem ( I think it was ETS ) that calculated 0 as a multiple of 5 since 5*0 = 0.

Factorize the number and one of all the factors is -ve.

2)Is -3 a multiple of 3? Is -12 a multiple of 3? Is zero a multiple of 3 ?(since 0:3=0 which is an integer)

"-3 a multiple of 3" is true. But "Is zero a multiple of 3" is false.


3)When looking for the divisors of a positive number we should look for negative numbers too? (if the question doesn't state oherwise). For example if the question is how many are the divisors of 12, we should anwser 6: (1,2,3,4,6,12) or the correct answer is 12? (-1,-2,-3,-4,-6,
-12,1,2,3,4,6,12).

This depends on the question. I have never encountered a question where it asks to find the -ve factors also.


thanks everybody!

dhayia , I think ) is a multiple , coz 0 with any number - +ve , -ve gives a valure 0...

1)yes, but how can a factor be negative? The theory says that PRIME factors can never be negative...

2)What about -12? is a multiple of 3, too? Or we start from -3?
If we should count negative multiples too, then if a question asks to find all the multiples of 3 up to 300, we should answer that they are infinite...
