Answer:
Step-by-step explanation: To find the prime factorization of 10, first create a factor tree with two branches.
When a number is even, it's often easiest to start by dividing by 2 to find factors.
Since 10 ÷ 2 is 5, we know that 2 and 5 are factors of 10 so we write 2 and 5 at the bottom of the branches.
Next, we circle any prime factors in the factor tree. Since both 2 and 5 are prime, we circle 2 and 5.
Since we have circles at the bottom of all of the branches, we are finished.
So the prime factorization of 10 is 2 × 5.
