Four of them.
Its factors are: 1 3 5 and 15
To find the factors of a number, you first need to split that number into its prime factors. In the case of 15, this produces: 15 = 3x5 The next step is to note that every factor of the number (apart from 1) is the product of any combination of its prime factors. Thus, the factors of 15 are: 1, 3, 5 and 15.
A factor = a number which can be divided into the given number with no remainder The factors of 15 are 1, 3, 5, and 15.
Well, darling, the number you're looking for is 15. It's less than 20, odd, and can be broken down into the prime factors 3 and 5. So, there you have it, a prime factor party with the number 15 strutting its stuff.
Any prime number to the 14th power has 15 factors, like 16384 or 4782969.
There's no such thing as "common factors" of a single number."Common" means "same for both".A "common" factor is a number that's a factor of at least two different numbers.The factors of 15 are: 1, 3, 5, and 15.Find another number that also has any of these as a factor, and you'll have a 'common' factor.
Various number has factors including 5 and 3 such as 15 and 45.
The number of different ways that you can arrange 15 different items is given by the permutations of 15 things taken 15 at a time. That is 15 factorial, or 1,307,674,368,000.
15 Factors of 15: 1, 3, 5, 15 15 = 1 x 15 15 = 3 x 5
Any whole number (integer) has factors. Factors are numbers that can be divided into another number. For example the factors of 15 are: 1, 3, 5 and 15 (1 times 15 and 3 times 5)
15 is a composite. Its factors are 1, 3, 5, and 15.
