Question

a Find the common factors of 3 and 9​

Answer 1

Answer:

3

Step-by-step explanation:

We found the factors and prime factorization of 3 and 9. The biggest common factor number is the GCF number. So the greatest common factor 3 and 9 is 3.

Answer 2

Answer:

1 and 3 are the common factors of 3 and 9.

Step-by-step explanation:

Factors:-

• The positive integers that can divide a number evenly (or completely).

Step 1 of 1

To find:-

The common factors of the numbers 3 and 9.

According to the question,

Consider the given numbers as follows:

3 and 9

Then, the factors of 3 are 1, 3.

Notice that there are 2 factors of the number 3, i.e., the number 3 is divisible by 1 and 3.

Similarly,

The factors of $9$ are $1, 3, 9$.

Notice that there are 3 factors of the number 9, i.e., the number 9 is divisible by 1, 3, and 9.

Thus, the common factors of 3 and 9 are 1, 3.

Final answer: 1 and 3 is the required answer.
