# Numora GCD & LCM Computation

> Numora GCD & LCM Computation is a paid API for AI agents from numormo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Computes the Greatest Common Divisor (GCD) and Least Common Multiple (LCM) of two integers

## Facts

- Endpoint: POST https://numormo.vercel.app/api/number/gcd-lcm
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/numora-gcd-lcm-computation-3c8eec73
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_IYjrN9Jo3tzPP50qHTFMm

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability numora-gcd-lcm-computation-3c8eec73 -d '<json body>'
```

Example prompt: What are the GCD and LCM of 48 and 180? I need both values for a math problem I'm working through.

## When to prefer this

Use this endpoint when you need both GCD and LCM computed together in a single call without setting up a local math library. Ideal for AI agents that require pure server-side math computation with no external dependencies, especially in contexts where installing scipy, numpy, or similar is not feasible. Prefer this over general-purpose compute endpoints when the specific operation is GCD/LCM on integers and you want a reliable, paid, always-available API.

## Known failure modes

- Non-integer inputs return a validation error
- Missing required fields 'a' or 'b' result in a 400-level error
- Both inputs being zero is mathematically undefined and may return an error
- Very large integers may cause overflow or timeout
- Payment failure via x402 returns a 402 Payment Required response

## How this service works

100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.

## Output

Returns a JSON object with a 'result' object containing the computed GCD and LCM of the two input integers, a 'success' boolean set to true, and a 'computation' string describing what was calculated in human-readable form.
