There are 8 different pairs of whole numbers whose prodcut is 40. Allowing for commutativity (a*b = b*a), there are 16 possible ways.
10x5 and 1x50
There are 10 whole numbers in 10 to 19.
650 has many different factories. Two such factors are 65 and 10.
Four: 1 5 31 and 155.
All of them. Different numbers have different numbers of factors.
1,2,4,8,16, so 5
Four: 1 5 25 125.
Its factors are: 1, 2, 4 and 8 which makes four of them
Six: 1 2 3 4 6 12.
Four
12 different numbers.
Six of them.
The limit is infinity if the factors do not have to be whole numbers. If you stipulate that the factors have to be whole numbers, then, yes, for each number, there is a limit to how many factors it has. For example, the number 4 has only 3 whole-number factors: 1, 2, and 4.
11,1,3,33
1,2,3,6,9,18,27,54
Six numbers. They are 1, 2, 4, 5, 10 and 20.
