The basketball team at a Middle School consists of seven students from the sixth, seventh, and eighth grades. If the product of their ages is 35,335,872, what is the sum of their ages?



Factor 35,335,872 remembering that the students are likely to be ten to fourteen years old. Thus, factor it as 112 x 123 x 132. Two students are 11 years old, three students are 12, and two students are 13. The sum of these ages is
2(11) + 3(12) + 2(13) = 84.
