Please check [Automaticly find a good Plaintext Modulus](https://openfhe.discourse.group/t/automaticly-find-a-good-plaintext-modulus/312) At a high level, the procedure for finding a plaintext modulus that is compatible with batching is explained on Slide 15 of the FHE integer arithmetic webinar at [Homomorphic Encryption for OpenFHE Users – OpenFHE.org](https://openfhe.org/portfolio-item/homomorphic-encryption-for-palisade-users-3/)

But this is needed only if you want to support component-wise multiplications (what batched encoding typically refers to). In the case of additions only, a different encoding can be used that does not have the constraint you mentioned. For example, p=2 would be allowed. In this case, you would use `MakeCoefPackedPlaintext` instead of `MakePackedPlaintext` when encoding the input vectors. See [Template Class CryptoContextImpl — OpenFHE documentation](https://openfhe-development.readthedocs.io/en/latest/api/classlbcrypto_1_1CryptoContextImpl.html?highlight=makecoefpackedplaintext#_CPPv4NK8lbcrypto17CryptoContextImpl23MakeCoefPackedPlaintextERKNSt6vectorI7int64_tEE6size_t8uint32_t) for more details (or search for code examples/unit tests in the library).
