Do you know your factor tricks? Match the number to its corresponding divisibility shortcut.
|
| A | B |
|---|
| 1 | Is it an integer? |
| 2 | Is it even? (Does it end in 2,4,6,8, or 0) |
| 3 | Do the digits eventually add up to 3, 6, or 9? |
| 4 | Can you divide the last 2 digits by 4? |
| 5 | Does it end in 5 or 0? |
| 6 | Is it divisible by 2 and 3? |
| 7 | 2 * the last digit, subtracted from the other digits--do you get a multiple of 7? |
