Numbers 12284 and 7656 when divided by a certain 3 digit number leaves the same remainder .Find the three digit number

To find the three-digit number \(n\) that, when dividing \(12284\) and \(7656\), leaves the same remainder, we need to consider the following:

If \(12284\) divided by \(n\) leaves a remainder \(r\), and \(7656\) divided by \(n\) leaves the same remainder \(r\), then:

\[
12284 = kn + r
\]
\[
7656 = mn + r
\]

where \(k\) and \(m\) are the quotients when \(12284\) and \(7656\) are divided by \(n\), respectively. 

By subtracting the second equation from the first, we eliminate \(r\):

\[
12284 - 7656 = kn + r - (mn + r)
\]

Simplifying this, we get:

\[
12284 - 7656 = (k - m)n
\]

\[
4628 = (k - m)n
\]

This means that \(n\) must be a divisor of \(4628\). Now, let's find the three-digit divisors of \(4628\).It appears that there are no three-digit divisors of \(4628\). This suggests that no three-digit number \(n\) exists such that when dividing \(12284\) and \(7656\), the same remainder is left.
