Using the Factor Calculator
For a perfect square, one factor pair contains the same number twice. The calculator lists that middle factor once rather than duplicating it.
Worked example
Use the example inputs below to reproduce this result. These are the form's starting values, not recommended targets. Changing your inputs updates your result above; this worked example stays fixed for comparison. Results are rounded for display.
Example inputs
- Integer
- 60
Example result
- Factors
- 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
Method and assumptions
Whole numbers only. Factors divide a number exactly. LCM(a,b) = a × b / GCF(a,b).
Keep exact values exact
Whole-number problems often need an exact answer rather than a rounded decimal. Check the permitted range and input notation before pasting a large number. A leading minus sign, a decimal point or a base prefix can change whether an entry is valid. Where the tool returns an exact integer or factorization, preserve that form for later calculations.
Common question
How can I tell whether a number is prime from its factors?
A prime integer greater than one has exactly two positive factors: one and itself. The number one has just one positive factor and is not prime.
