A factor of a number is another number that divides the original number evenly. Factors are numbers that can be multiplied together to give the original number. Factoring is a key math operation used in many areas like finding common divisors, solving equations, and simplifying fractions.
For instance, the factors of 100 include 1, 2, 4, 5, 10, 20, 25, 50, and 100. These numbers can be multiplied in different ways to equal 100.

Steps to Calculate the Factors of 100
-
Begin with the number 1 and divide 100 by it. If the result is a whole number, it's a factor of 100.
-
Divide 100 by 2. If the result is a whole number, it's also a factor of 100.
-
Repeat this with each consecutive whole number, dividing 100 and checking if the result is whole.
-
Continue until you've checked up to 100.
-
All the whole numbers you get from this process are factors of 100.
It's easier to find factors of 100 because it divides evenly by many numbers. Larger numbers can take more time to find all their factors.
Factors of 100 by Prime Factorization
Prime factorization involves breaking down a number into its prime components to find its factors. To determine the factors of 100 using prime factorization, follow these steps:
-
Identify the prime factors of 100: 2 x 2 x 5 x 5.
-
Use these prime factors to create all possible combinations of factors by multiplying pairs of 2's and 5's:
1 x 100 = 100 2 x 50 = 100 4 x 25 = 100 5 x 20 = 100 10 x 10 = 100
-
The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100.
Prime factorization not only helps in finding factors but also plays a role in other mathematical tasks like finding the greatest common divisor, simplifying fractions, and solving equations.
