To answer this question fully would be tediously time-consuming and counterproductive. The purpose of this forum is to provide you with information, perhaps a few examples, so that you can complete the task yourself.

All the numbers up to 100 are factors in some numbers up to 100. For example, 1 is a factor of every number and 2 is a factor of all the even numbers. The numbers greater than 50 are only factors of themselves among the numbers up to 100, 95 is only a factor of itself, because the next number for which it is a factor is 190, which is greater than 100.
Three numbers.
The common factors are: 1, 2, 4
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. The factors of 45 are 1, 3, 5, 9, 15, and 45. Factors are numbers that can be multiplied together to give the original number.
60, 72, 84, 90 and 96 each have 12 factors.
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.
Each of the 25 prime numbers from 1 to 100 has exactly two factors, 1 and the number itself. The other 75 numbers from 1 to 100 are not prime numbers because none of them have exactly two factors.
4, 9, 25, and 49 are all of the numbers between 1 and 100 having 3 factors.
The only common factor of these numbers is 1.
There aren't any numbers between 1 and 100 with 16 factors.
There are 25 prime numbers between 1 and 100, all of them can be factors.
No numbers between 1 and 100 have exactly eleven factors. 60, 72, 84, 90 and 96 each have twelve factors.
The maximum number of different factors is 12 and there are 5 numbers in 1-100 which have 12 factors.
numbers are 5,8,10,14,21,22,26,27,33,34,35,38,39,46,51,55,57,65,69,74,77,85,91,95. total 24.
Only 1.
Both 25 and 4 are factors of 100 and are square numbers, 25 is 52 and 4 is 22. 100 and 1 are also factors of 100, and are also square numbers: 1 is 12 and 100 is 102.
