Answer
$30 = 2 \cdot 3 \cdot 5$
Work Step by Step
The $\textit{prime factorization}$ of a number is obtained by writing the number as a product of primes.
To determine the prime factorization of $30$ we write the number as a product of factors and continue the process until all factors are prime numbers.
We start by writing $30$ as a product of two numbers:
$30=2\cdot 15$.
The number $2$ is prime, but $15$ is not. So we write $15=3\cdot 5$:
$30=2\cdot 3\cdot 5$.
Now each factor is a prime number, therefore the prime factorization of $30$ is $2\cdot 3\cdot 5$.
