Video Summary

The problem involves determining Mary's current age given a future scenario. Mary's daughter has just given birth to a granddaughter. In two years, their ages' product will be 2024, and the granddaughter will be 2. Let's express Mary's age as 2M and her daughter's age as 2D. In two years, the product of their ages (all even numbers) will be expressed as 2 <em> 2D </em> 2M = 2024. Prime factorization of 2024 is 2 <em> 2 </em> 11 <em> 2 </em> 23, aligning with their age product. Thus, Mary will be 46 in two years, and currently, she is 44.
