Array integer LCM

array-integer-lcm · version 1.0.0 · Numbers & math · free, no key needed

Compute the non-negative least common multiple of an array of canonical integer strings.

Use when you need to: array integer lcm · lcm of an array of integers · least common multiple of a list.

Supported

• array integer lcm
• lcm of an array of integers
• least common multiple of a list
• n-ary lcm

Not supported

• greatest common divisor
• lcm of two integers
• floating-point lcm

Behavior

• Input values is an array of canonical base-10 integer strings with at most 10000 items.
• The input -0 is accepted per item and canonicalized to 0 before evaluation.
• The empty array has lcm 1, the multiplicative identity.
• If any value is 0, the result is 0, matching the two-argument convention lcm(0, n) = 0.
• Otherwise the lcm is computed pairwise left to right as |a / gcd(a, b) * b| and is independent of order.
• The result is the non-negative least common multiple as a canonical integer string, at most 1000 digits.

Input

• values (array of string, required): max items 10000; each max length 1001; each pattern ^-?(0|[1-9][0-9]*)$

Output

• value (string, required)

Limits

• max items: 10000
• max digits: 1000

Example

Request input:

{
  "values": [
    "4",
    "6",
    "10"
  ]
}

Response:

{
  "result": {
    "value": "60"
  }
}
