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.
Factors of 15 are: 1 3 5 and 15 of which 3 and 5 are prime factors
The factors of 15 are: 1, 3, 5, and 15.The prime factors of 15 are: 3 and 5.The factors of 21 are: 1, 3, 7, and 21.The prime factors of 21 are: 3 and 7.
The common factors of 6 and 15 is 1 and 3 that's all
The factors of 4 are 1, 2, 4 The factors of 15 are 1, 3, 5, 15
There are 15 factors in all.
2,500 has 15 factors.
Two prime factors.
The answer is 4. These factors are 1, 3, 5, 15.It has four factors and they are: 1, 3, 5 and 15
1, 3, 5, 15
Four of them.
Its factors are: 1 3 5 and 15
4
The answer to this is 3
Four
8.
It is factors are: 1, 3, 5 and 15 which makes four of them
