Squares of prime numbers have three factors.
It is impossible to determine what number has the most factors because there are an infinite number of numbers.
A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 3 are 1 and 3. The factors of 4 are 1, 2, and 4. The only common factor is 1.
A factor is a divisor - a number that will evenly divide into another number. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 21 are 1, 3, 7, and 21. The factors of 27 are 1, 3, 9, and 27. The common factors are 1 and 3. This means that the greatest common factor is 3.
limiting factors
A prime number only has two factors. If the number you're looking at has more than two factors, it is not prime.
You determine it by the denominator.

One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 33 are 1, 3, 11, and 33. The factors 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The common factors are 1 and 3.
The Number of factors, (That is the number of pairs, such as 2= 1x2, 2x1), is equal to the number of rectangular arrays which can be made for each composite number. As such, the number of factors in the number 9 is 3, (1,3,9), and the number of rectangular arrays is also three (1x9, 9x1,3x3). Hope this helps!
Odd. I determined my answer by looking at the number of factors of a square number.
To determine how many digits in the number 123,456,789 are factors of the number itself, we first identify the individual digits: 1, 2, 3, 4, 5, 6, 7, 8, and 9. We then check which of these digits are factors of 123,456,789. The digits that are factors are 1, 3, and 9. Therefore, there are three digits in 123,456,789 that are factors of the number.
Composite, 1881 divided by 3 equals 627.1881 is divisible by 9 as well. You can determine this by adding up the digits:1 + 8 + 8 + 1 = 18 (which is divisible by 9, so the original number is divisible by 9).This trick works to determine if a number is divisible by 3 as well (if the sum of digits is divisible by 3, then the number is divisible by 3).Since 1881 has factors of 1881, 1, 9 and (1881 / 9 = 209) and you can stop there; you have determined that the number is not prime. {By the way, 11 & 19 are also factors}Every number has factors of itself and 1. If it has other factors beside that, then it is composite. If those are the only 2 factors, then the number is prime.If a number X is divisible by another number M, then M is a factor of X.
To find the common factors of 123 and 555, we first need to determine the factors of each number. The factors of 123 are 1, 3, 41, and 123. The factors of 555 are 1, 3, 5, 15, 37, 111, and 555. The common factors of 123 and 555 are 1 and 3. Therefore, they have 2 common factors.
