Three factors in common.
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.
There are two.
An infinite number.
A composite number has three or more factors.
11,1,3,33
120 is the lowest of many.
1,2,3,6,9,18,27,54
The positive integer factors of 54 are: 1, 2, 3, 6, 9, 18, 27, 54The positive integer factors of 126 are: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126Therefore, their common whole-number factors are: 1, 2, 3, 6, 9, and 18.
Divide both sides of the ratio by common factors. Here are common factors of 24 and 30: 2, 3, & 6. The equivalent ratios of 24:30 (using division) are:12:158 : 104 : 5
the number 90 has the most factors under 100
75's factors are: 1,3,5,15,25,75 so it has 6 factors
