What Is a Factor Calculator?
A factor calculator is an online calculator that identifies every whole number that divides another number exactly without leaving a remainder.
For example, the factors of 24 are:
1, 2, 3, 4, 6, 8, 12, and 24
Each of these numbers divides 24 evenly.
Besides finding all factors, many modern factor calculators also include additional mathematical tools such as:
- Prime factorization
- Factor tree
- Greatest Common Factor (GCF)
- Least Common Multiple (LCM)
- Divisibility checker
- Number comparison
- Calculation history
Having all these features in one place makes solving math problems much faster.

Factor Calculation Formulas
Although the calculator performs all calculations automatically, understanding the formulas can help improve mathematical knowledge.
Finding Factors
A factor is any whole number that divides another number exactly.
If Number ÷ Factor = Whole Number, then it is a factor.
Example:
24 ÷ 6 = 4
Since the answer is a whole number, 6 is a factor of 24.
Prime Factorization
Prime factorization means repeatedly dividing a number by the smallest possible prime number until only prime numbers remain.
Example:
60
= 2 × 30
= 2 × 2 × 15
= 2 × 2 × 3 × 5
Greatest Common Factor (GCF)
The Greatest Common Factor is the largest factor shared by two or more numbers.
Example:
Factors of 24:
1, 2, 3, 4, 6, 8, 12, 24
Factors of 36:
1, 2, 3, 4, 6, 9, 12, 18, 36
Largest common factor = 12
Least Common Multiple (LCM)
A common formula for two numbers is:
LCM = (Number A × Number B) ÷ GCF
Example:
15 × 20 = 300
GCF = 5
LCM = 300 ÷ 5
LCM = 60
Practical Calculation Examples
Real examples make the factor calculator easier to understand.
Example 1: Factors of 24
Input:
24
Output:
1, 2, 3, 4, 6, 8, 12, 24
Total factors:
8
Example 2: Prime Factors of 60
Input:
60
Output:
2 × 2 × 3 × 5
This is the prime factorization of 60.
Example 3: GCF of 24 and 36
Input:
24 and 36
Output:
12
The calculator immediately identifies the largest shared factor.
Example 4: LCM of 15 and 20
Input:
15 and 20
Output:
60
This result is useful for fraction calculations and scheduling problems.
Example 5: Divisibility Rules
