Provide a real world example of where knowledge of integers is necessary

An integer is a whole number, a number that is not a fraction. So there are many real world examples of where knowledge of integers is necessary, like math problems with whole numbers

went on a trip this weekend and had to drive 600 kilometers. On part of the trip the speed limit was 100 kilometers per hour and on another stretch of road it was 110 kilometers per hour.

GCF = 4

for the values 8, 12, 20

Step-by-step explanation:

The factors of 8 are: 1, 2, 4, 8

The factors of 12 are: 1, 2, 3, 4, 6, 12

The factors of 20 are: 1, 2, 4, 5, 10, 20

Then the greatest common factor is 4.
