What is my number?
Clue 1: My number is a multiple of 5, but it does not end in 5.
Clue 2: The prime factorization of my number is a string of three numbers.
Clue 3: Two of the numbers in the prime factorization are the same.
Clue 4: My number is bigger than the seventh square number.
I would start with the seventh square number
1, 4, 9, 16, 25, 36, 49
so it is bigger than 49
50, 60, 70, and so on. See which has three prime factors, two of which are the same.
how can i make a factorization string for the number 48
I believe it is 100
