Question

write the prime factorization of 4. order the factors from least to greatest (for example, 2 × 2 × 3 × 5).

Explanation:

Step1: Recall prime factorization

Prime factorization means expressing a number as a product of prime numbers. A prime number is a number greater than 1 that has no positive divisors other than 1 and itself. For 4, we start by dividing it by the smallest prime number, which is 2.
$4\div2 = 2$

Step2: Continue factoring

Now we factor the quotient 2, which is also a prime number. So we can't factor it further. So the prime factors of 4 are 2 and 2.

Answer:

$2\times2$
