by finding the half of the number and list the factors all the way to that number
infinity. it has every factor
A friendly number is a number that has a lot of factors depending on the size of the number. For example, eight is a friendly number. Its factors are 8,4,2,1. 7 isn't because its only factors are 7 and 1.
Probably, but that's not the reason. An abundant number is less than the sum of its proper factors.
There are many numbers with 12 prime factors. They are very, very big. The number with the lowest 12 prime factors is 7420738134810 if you start with 2 as the lowest factor. If you start with 1 as the lowest factor, then the number is 200560490130. 2048 has 12 factors.
Yes it is a real number and it is a number bigger than infinity by a whole lot!
This will vary greatly depending on a number of factors.
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.
Factors of the number will also be factors of the number's multiples. Multiples of the number will also be multiples of the number's factors.
Too big to number. A whole lot.
