The positive integer factors of 30 are: 1 2 3 5 6 10 15 30 The odd factors are therefore 1, 3, 5, 15
If you include 30, both 24 and and 30 have 8 factors, the most in that range.
An odd number of odd numbers can't add up to an even number.
28
The number with the most factors between 21 and 40 is 30. Factors of a number are the numbers that can divide the original number without leaving a remainder. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30, giving it a total of 8 factors, which is the highest among the numbers between 21 and 40.
No.
The numbers between 10 and 30 that have exactly 5 factors are 16 and 25. The number 16 has factors 1, 2, 4, 8, and 16. The number 25 has factors 1, 5, 25, but since it is a perfect square, it also includes the repeated factor of 5. These are the only two numbers between 10 and 30 that have exactly 5 factors.
23 is an odd number between 10 and 30 that gives a remainder of 2 when divided by 7.
There are 7 odd numbers between 16 and 30. To find this, you can subtract the largest odd number less than 30 (29) from the smallest odd number greater than 16 (17), then divide by 2 and add 1. So, (29-17)/2 + 1 = 7 odd numbers between 16 and 30.
The positive integer factors of 30 are: 1 2 3 5 6 10 15 30 The odd factors are therefore 1, 3, 5, 15
The factors of a number cannot be greater than the number itself. So there are no factors of 4 between 30 and 50.
15
Even number.
21, 23, 25, 27, 29
21 23 25 27 29
30 is an even number.
36 is a composite number between 30 and 40 because its factors are 1,2,3,4,6,9,12,18,36
