Question

Find all the factors of 15 and tell how?​

Answer 1

Answer:

Factors of 15: 1, 3, 5 and 15

Prime Factorization of 15: 3 × 5

Step-by-step explanation:

In order to find all the factors of 15, we have to make all the possible pairs of numbers and multiply them to see if the result is 15 or not.

For example, 1 × 15 = 15 and 2 × 7.5 = 15, but since a factor cannot be a decimal number, 2 cannot be a factor of 15.

Similarly, 3 × 5 = 15, and 15 × 1 = 15

That’s how you know that no other number apart from 1,3, 5, and 15 is a factor of 15

Answer 2

Answer:

mark me brainliest please
