Find the smallest positive integer that is one less than a number that is a multiple of each of \(3, 5, 7, 9, 11, \ \text{and} \ 13\).
If you want to find an integer that is a multiple of 5, 7 9, 11, and 13, multiply them together: 45045.
(You can skip 3, because any multiply of 9 will be a multiple of 3.)
Subtracting 1: 45044.
9*5*7*11*13=45045
45045-1=45044
