only 25
16 and 36 also have an odd number of factors, but both of those have more than 3.
25 it's factors are 1, 5,and 25. That's a number between 12 and 40 that has only 3 factors
25
25 does.
The only number between 30 and 40 with distinct prime factors which add up to 12 is 35.
Square numbers have an odd number of factors. Other numbers have an even number of factors. The squares between 12 and 40 include 16, 25, and 36. If the number has only three factors, it must be the square of a prime number, since two of the factors will be 1 and itself, so if there is only one more factor, this third number cannot have factors itself. This means the number must be 25, whose factors are 1, 5, and 25. Response: 24 has (at least) three factors - 1, 2, 3, 4, 6, 8, 12, and 24 .
These numbers between 1 and 40 have an odd number of factors: 4, 9, 16, 25, 36.
That number is 36.
36 has nine factors
36 is a composite number between 30 and 40 because its factors are 1,2,3,4,6,9,12,18,36
Any number between 30 and 40 can be a factor. The common factors of 30 and 40 are 1, 2, 5 and 10.
25
There are 14 even numbers between 12 and 40. To calculate this, you can use the formula for finding the number of integers in a range: (largest number - smallest number) / 2 + 1. In this case, (40 - 12) / 2 + 1 = 28 / 2 + 1 = 14. So, there are 14 even numbers between 12 and 40.
