The complete answer to this question would be tediously time-consuming and counterproductive. The purpose of this forum is to provide you with information and perhaps a few examples so that you can solve such problems on your own.

The factors of 144 are: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
The factors of 144 are 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144.
They are not prime numbers because they have other factors aside from 1 and themselves.
Looking at 144, you can quickly see that it is an even number and all even numbers are divided by 2. Since prime numbers only have two factors (1 and the number itself), 144 has to be a composite number.
144 has 15 factors: 1 2 3 4 6 8 9 12 16 18 24 36 48 72 144.
2 and 3
Any of its factors
144: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
Those numbers (factors) are: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72 and 144.
The number 144 can be divided by 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144. These are all the factors of 144, which are the numbers that can evenly divide into 144 without leaving a remainder. Factors are pairs of numbers that, when multiplied together, result in the original number.
The factors of 225 are 1, 3, 5, 9, 15, 25, 45, 75, and 225. The factors of 144 are 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144. Factors are numbers that can be multiplied together to give the original number, and both 225 and 144 have multiple factors due to their composite nature.
144 is a composite number. A prime number has exactly two distinct factors, which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
