To determine if 4, 8, 11, and 12 are factors of the given numbers, we need to divide each number by these potential factors. A number is a factor if it divides evenly into the number, meaning there is no remainder.

180 :


4 : 180 divided by 4 equals 45, so 4 is a factor.
8 : 180 divided by 8 equals 22.5, so 8 is not a factor.
11 : 180 divided by 11 equals approximately 16.36, so 11 is not a factor.
12 : 180 divided by 12 equals 15, so 12 is a factor.


275 :


4 : 275 divided by 4 equals 68.75, so 4 is not a factor.
8 : 275 divided by 8 equals 34.375, so 8 is not a factor.
11 : 275 divided by 11 equals 25, so 11 is a factor.
12 : 275 divided by 12 equals approximately 22.92, so 12 is not a factor.


360 :


4 : 360 divided by 4 equals 90, so 4 is a factor.
8 : 360 divided by 8 equals 45, so 8 is a factor.
11 : 360 divided by 11 equals approximately 32.73, so 11 is not a factor.
12 : 360 divided by 12 equals 30, so 12 is a factor.


688 :


4 : 688 divided by 4 equals 172, so 4 is a factor.
8 : 688 divided by 8 equals 86, so 8 is a factor.
11 : 688 divided by 11 equals approximately 62.55, so 11 is not a factor.
12 : 688 divided by 12 equals approximately 57.33, so 12 is not a factor.


440 :


4 : 440 divided by 4 equals 110, so 4 is a factor.
8 : 440 divided by 8 equals 55, so 8 is a factor.
11 : 440 divided by 11 equals 40, so 11 is a factor.
12 : 440 divided by 12 equals approximately 36.67, so 12 is not a factor.
