21 is the smallest #. 147 / 21 = 7.
45,360
The factors of 21 are: 1, 3, 7, 21.
4 factors they are 1,3,7 and 21
I think that it is 4
The smallest number with 16 factors is Andrew's Mom.
28 is the smallest number which satisfies these constraints, the next smallest numbers are 30, 32, and 36. This can be eaily calculated as the divisor function is a series on oeis A000005. 21 hsa 4 factors; 1, 3, 7, 21 as it is semi prime.
The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210
21 is the smallest #. 147 / 21 = 7.

240 is the smallest number with twenty factors.
Every number has factors. They are endless.
The smallest number that has exactly eight factors is 24. The factors of 1,2,3,4,6,8,12, and 24
A factor is a divisor - a number that will evenly divide into another number. The factors of 21 are 1, 3, 7, and 21. The factors of 49 are 1, 7, and 49. The common factors are 1 and 7. The least (or smallest) common factor is 1. Because the smallest factor of any integer is usually 1, the least common factor of two or more integers is also usually 1.
240 has 20 factors.
The smallest number that has 1,230 and 36 as factors is 7,380.
If you mean 2, 3 and 7 as factors then the smallest number is 42
