Find the least possible number which when divisible by 2, 4, 6 and 8, it leaves the remainder 1, 3, 5 and 7 respectively.

Explanation

To solve the problem of finding the least possible number that leaves specific remainders when divided by 2, 4, 6, and 8, we can follow these steps:

### Step 1: Understand the problem
We need to find a number \( x \) such that:
- \( x \mod 2 = 1 \)
- \( x \mod 4 = 3 \)
- \( x \mod 6 = 5 \)
- \( x \mod 8 = 7 \)
