24 does.
which of the numbers 19 21 23 and 25 has the most factors
Its factors are: 1 3 7 and 21 Note that 3 and 7 are prime numbers
The four factors common to the numbers 9, 15, 18, 21, 30, 35, 36, 42, and 49 are 1, 3, 7, and 21. Each of these numbers can be divided evenly by these factors. However, they are not the only factors; these are simply the ones that appear in all the numbers listed.
21 and 28 have 7 as a factor.
The only common factor of all three numbers is 3. (The numbers 21 and 63 share all of the factors of 21 : 1, 3, 7, and 21.)
21 does.
21 has the most factors of the given numbers.
Out of that group, 21 has the most factors.
21 has the most factors of the four numbers. 19 has 2 factors (1 and 19) 21 has 4 factors (1, 3, 7, 21) 23 has 2 factors (1, 23) 25 has 3 factors (1, 5, 25)
Four of them.
which of the numbers 19 21 23 and 25 has the most factors
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.
21 has more factors than the others.
21 has more factors than the others.
7x3 = 21 All numbers from 1-400 (399 total) that are factors of 21: 399/21 = 19
The number 21 would be the answer. 19 and 23 only have two factors, 1 and themselves, as they are prime numbers. 25 only has 1, 25 and 5. 21 has 1, 21, 3 and 7 for 4 possible factors.
The most common factors of 21 and 24 are the numbers that divide both 21 and 24 without leaving a remainder. The factors of 21 are 1, 3, 7, and 21, while the factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The common factors of 21 and 24 are 1 and 3.
