The number 4 only has 3 (positive) factors:
4×1=4
1×4=4
2×2=4
They are 1, 2 and 4
If you include negatives:
-4×-1=4
-2×-2=4
Then it has 6 factors

The number 4 has three factors, and they include : 1, 2, and 4.

1 × 4 = 4
2 × 2 = 4
4 × 1 = 4

There are only three factors of 4. Nothing preceding that. There are no other possible factors of 4, therefore, that is incorrect, because 4 only has three factors.
