Repeat the above with the following modification—use multiplication instead of addition. Here is an example: 7391928 = 7 * 3 * 9 * 1 * 9 * 2 * 8 = 27216 27216 = 2 * 7 * 2 * 1 * 6 = 168 168 = 1 * 6 * 8...

Repeat the above with the following modification—use multiplication instead

of addition. Here is an example:

7391928 = 7 * 3 * 9 * 1 * 9 * 2 * 8 = 27216

27216 = 2 * 7 * 2 * 1 * 6 = 168

168 = 1 * 6 * 8 = 48

48 = 4 * 8 = 32

32 = 3 * 2 = 6.
