Adam says that the number 4 has four factors. Explain why this statment is incorret

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.

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
