Answer: This is an easy one, its either 21, 21 and a half, or 22, if not than its at least in the 20s.
Step-by-step explanation:
The GCF is the largest number that both will divide into. Eight is the larger of the two, but 52 is not divisible by 8. The next highest value is 4. 8÷4=2 and 52÷4=13. Therefore, the GCF is 4.
If line segment EF is 28 and F is halfway through the line, then segment EF will be half of 28. So segment EF=14
