Question

Glenn’s favorite number is very special because it reminds him of the day his daughter, Sarah, was born. The factors of this number do not repeat, and all the prime numbers are less than 12. What is Glenn’s number? When was Sarah born?

Answer 1

2/3/10

Explanation:

the number is such that its factors do not repeat and factors are all prime numbers less than 12.

prime numbers less than 12 are 2,3,5,7,11

so if the number is N then

N= 2×3×5×7×11= 2,310

Hence the Number N is 2310

and DOB of the daughter must be 2/3/10
