The factors of 48 are 1,2,3,4,6,8,12,16,24 and 48.
There is an infinite amount.
The perfect numbers less than 100 are 6 and 28.
(1,20),2,10,4,5
1,2,3,5,6,9,10,15,18,30,45,90
2 and 5 are the prime factors of 100.
The factors of all of the numbers from 1 to 100 are all of the numbers from 1 to 50.
All of the numbers from 1 to 100 are the factors in the set of numbers from 2 to 100.
4, 9, 25, 49
All non-zero numbers have factors. These can be written down in a list. That would be known as a list of factors.
Prime squares: 4, 9, 25 and 49
All of them. Different numbers have different numbers of factors.
All numbers have factors.
The prime factors of 100 are: 2,5
That's an infinite list.
That's an infinite list.
I wrote out all the factors of all the numbers from 1 to 100 and counted them.
