The factors of 16 are 1, 2, 4, 8, and 16. The factors of 28 are 1, 2, 4, 7, 14, and 28.
The greatest common factor of 16 and 28 is 4
From the beginning of a period to the beginning of the next one is on average 28 days.
the uterine lining builds-up during the proliferate phase of the menstrual cycle. Everyone's menstrual cycles are different, but during a 28 day cycle this phase would be around days 16-28.
