Question
The factors of 45 are___________.
- 1 × 45, 5 × 9, 3 × 15
- 3 × 1, 45 × 1, 2 × 5
- 3 × 1, 4 × 3, 1 × 45
- 45 × 1, 3 × 9, 9 × 9
Hint:
A factor is a number that you multiply with another number to get a product. Then the numbers are the factors of the product.
The correct answer is: 1 × 45, 5 × 9, 3 × 15
To find the factors of 45 we can write the 45 as the product of two numbers
like 1 × 45 = 45, 5 × 9 = 45, 3 × 15 = 45
So, 1 × 45, 5 × 9, 3 × 15 are the factors of 45.
