Answer
$2\times3\times5$
Work Step by Step
A number is prime if it has only two factors: 1 and itself.
We know that the factors of 30 are 1, 2, 3, 5, 6, 10, 15 and 30.
2 is a prime number, so we can divide 30 by 2
$30\div2=15$
The factors of 15 are 1, 3, 5, 15. Since 3 is a prime number, divide by 3.
$15\div3=5$
5 is also a prime number
Therefore, the prime factorization of 30 is $2\times3\times5$.
