Math & Numbers

Extended Euclidean Algorithm (ax + by = gcd(a, b))

Bézout coefficients for any-sign integers with the full division-step table, lcm, and optional linear Diophantine solving (particular + general solution).

text· Text resultOpen tool

Quick start

Call this tool from your code in three languages.

cURL
curl -X POST 'https://api.elysiatools.com/en/api/tools/extended-euclidean-algorithm' \
  -H 'Content-Type: application/json' \
  -d '{"a":"240","b":"46","c":"e.g. 4 — leave empty for the plain Bézout identity","style":"steps"}'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

Endpoint

HTTP
POST https://api.elysiatools.com/en/api/tools/extended-euclidean-algorithm

Parameters

NameTypeRequiredDescription
atextYesFirst integer; negative values are supported.
btextYesSecond integer; negative values are supported.
ctextNoOptional target: solves ax + by = c when gcd(a, b) divides c.
styleselectYes—

MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

Server configuration

Add this block to your MCP client configuration:

mcp.json
{
  "mcpServers": {
    "elysiatools-extended-euclidean-algorithm": {
      "name": "extended-euclidean-algorithm",
      "description": "Bézout coefficients for any-sign integers with the full division-step table, lcm, and optional linear Diophantine solving (particular + general solution).",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=extended-euclidean-algorithm",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call
{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "extended-euclidean-algorithm",
    "arguments": {
  "a": "240",
  "b": "46",
  "c": "e.g. 4 — leave empty for the plain Bézout identity",
  "style": "steps"
}
  }
}
Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
