# Divisors

The sum of all divisors unknown odd number is 2112. Determine sum of all divisors of number which is twice of unknown numbers.

Result

x =  6336

#### Solution:

$\ \\ n = 1841 \ \\ A = \{ 1, 7, 263, 1841 \} \ \\ B = \{ 1, 2, 7, 14, 263, 526, 1841, 3682 \} \ \\ x = 2112 + 2\cdot 2112 = 3\cdot 2112 = 6336$
