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.

The term common factors specifically refers to the factors shared by two or more numbers. Since 144 is a single number, you could say that it shares all of its factors with itself.The factors of 144 are: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144.
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.
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.
