We are asked which of the given options is a factor of the following number
Recall that a factor of a number is a number that evenly divides that number.
Meaning that there will no remainder when you divide a number with its factor.
Let us check each of the given options whether it is a factor of the given number or not.
Option A. 3
60070/3 = 20023.33
3 does not divide 60070 evenly so it is not a factor.
Option B. 4
60070/4 = 15017.5
4 does not divide 60070 evenly so it is not a factor.
Option C. 5
60070/5 = 12014
As you can see, 5 divides 60070 evenly so it is a factor.
Option D. 6
60070/6 = 10011.67
6 does not divide 60070 evenly so it is not a factor.
Therefore, the correct option is C, 5 is a factor of 60070.
