Twelve distinct factors.
There can be infinitely many distinct factors.
"Distinct" in this case means different. Sometimes factors are repeated. Square numbers have a factor pair that is the same number twice. When we write out the list of numbers, we don't write that number twice. The factor pairs of 100 are (100,1)(50,2)(25,4)(20,5)(10,10) The distinct factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, 100
