Does there exist natural numbers $a,b,c$ all greater than $10^{10}$ such that their product is divisible by each of these numbers increased by $2012$?
1. We need to determine if there exist natural numbers \(a, b, c\) all greater than \(10^{10}\) such that their product is divisible by each of these numbers increased by 2012. We generalize the problem to finding natural numbers \(a, b, c\) all greater than \(m\) such that their product is divisible by each of these numbers increased by \(n\), where \(m, n \in \mathbb{N}\).

2. Let's consider the numbers \(a, b, c\) as multiples of \(n\). Specifically, let:
   \[
   a = n(\lambda^2 - 1), \quad b = n\lambda, \quad c = n\lambda
   \]
   where \(\lambda\) is an arbitrarily large natural number.

3. We need to check if \(a \cdot b \cdot c\) is divisible by \(a+n\), \(b+n\), and \(c+n\). Substituting the values of \(a, b, c\), we get:
   \[
   a + n = n(\lambda^2 - 1) + n = n\lambda^2
   \]
   \[
   b + n = n\lambda + n = n(\lambda + 1)
   \]
   \[
   c + n = n\lambda + n = n(\lambda + 1)
   \]

4. Now, we need to check if \(a \cdot b \cdot c\) is divisible by \(n\lambda^2\) and \(n(\lambda + 1)\). The product \(a \cdot b \cdot c\) is:
   \[
   a \cdot b \cdot c = n(\lambda^2 - 1) \cdot n\lambda \cdot n\lambda = n^3 \lambda^2 (\lambda^2 - 1)
   \]

5. We need to verify the divisibility conditions:
   \[
   n^3 \lambda^2 (\lambda^2 - 1) \div n\lambda^2
   \]
   \[
   n^3 \lambda^2 (\lambda^2 - 1) \div n(\lambda + 1)
   \]

6. Simplifying the first condition:
   \[
   n^3 \lambda^2 (\lambda^2 - 1) \div n\lambda^2 \implies n^2 (\lambda^2 - 1)
   \]
   Since \(n^2 (\lambda^2 - 1)\) is clearly divisible by \(n\lambda^2\), the first condition is satisfied.

7. Simplifying the second condition:
   \[
   n^3 \lambda^2 (\lambda^2 - 1) \div n(\lambda + 1) \implies n^2 \lambda^2 (\lambda^2 - 1) \div (\lambda + 1)
   \]
   Since \(\lambda\) is arbitrarily large, \(\lambda^2 - 1\) is divisible by \(\lambda + 1\) because:
   \[
   \lambda^2 - 1 = (\lambda - 1)(\lambda + 1)
   \]
   Thus, \(n^2 \lambda^2 (\lambda^2 - 1)\) is divisible by \(n(\lambda + 1)\).

8. Therefore, the conditions are satisfied, and such natural numbers \(a, b, c\) exist.

The final answer is \( \boxed{ a = n(\lambda^2 - 1), b = n\lambda, c = n\lambda } \) where \(\lambda\) is an arbitrarily large natural number.
