Please check the attached figure a to visualize the array grid for 5, 7 and 11.
Step-by-step explanation:
As the given number be 5, 7 and 11.
An array is basically the display of things in rows and columns. Students tend to draw arrays for multiples of a given number.
For example, 2 × 1 means the objects are placed in two rows and 1 column.
The numbers 5, 7 and 11 are prime numbers as they have only two factors
- A prime number consists of just two factors, 1 and the number itself
- For example, 3 is prime number because the only factors of 3 are 1 and 3
So,
As the factors of 5 are 1 and 5. Therefore, the possible number of drawing all the possible arrays of 5 will be two which are
- 1 × 5 and 5 × 1
As the factors of 7 are 1 and 7. Therefore, the possible number of drawing all the possible arrays of 7 will be two which are
- 1 × 7 and 7 × 1
As the factors of 11 are 1 and 11. Therefore, the possible number of drawing all the possible arrays of 11 will be two which are
- 1 × 11 and 11 × 1
Please check the attached figure a to visualize the array grids for 5, 7, and 11.
