4. 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 60.

Answer 1

Factoring a number means to break it up into numbers that can be multiplied together to get the original number.

Factors of 60 are : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Assuming that Hugh wrote all the factors from 1 to 60.

So, none of the options is Hugh's list. Option 1 is wrong.

Option 2 has 2 and 60 missing

Option 3 is wrong as 7 and 14 are not factor of 60.

Option 4 has 30 missing.
