The factors of 8 is a fundamental concept in mathematics. Factors are numbers that can be multiplied together to produce another number. For 8, the factors are 1, 2, 4, and 8. This means that 8 can be divided evenly by these numbers without leaving a remainder. Identifying factors is essential for various mathematical applications, including simplifying fractions, solving equations, and understanding number properties. Whether you’re a student or someone looking to refresh their math skills, knowing the factors of 8 provides a solid foundation for more advanced mathematical concepts.
The factors of 8 are the numbers that divide 8 exactly without leaving a remainder. These factors are 1, 2, 4, and 8. To determine the factors, you start with the smallest number, 1, which is a factor of every whole number. Next, you check 2, which divides 8 evenly, giving 4. Since 4 is also an even division of 8, it is a factor. Finally, 8 itself is a factor because any number is always divisible by itself. Therefore, the complete list of factors for 8 includes 1, 2, 4, and 8.
The factor pairs of 8 are (1, 8) and (2, 4).
In multiplication, 1 times 8 equals 8, forming the factor pair (1, 8).

Since 8 is not a prime number, it has multiple factor pairs: (1, 8) and (2, 4).
The unique factor pairs of 8 are (1, 8) and (2, 4).
Calculating the prime factors of a number involves breaking down the number into its basic building blocks, which are prime numbers. Prime numbers are numbers greater than 1 that have no divisors other than 1 and themselves. Here’s a step-by-step guide to finding the prime factors of 8:

Calculating the prime factors of a number involves breaking down the number into its basic building blocks, which are prime numbers. Prime numbers are numbers greater than 1 that have no divisors other than 1 and themselves. Here’s a step-by-step guide to finding the prime factors of 8:
Begin by identifying the smallest prime number, which is 2.
Divide 8 by 2. The result is 4, since 8 ÷ 2 = 4.
Take the result from the previous step, which is 4, and divide it by 2 again. This gives 2, since 4 ÷ 2 = 2.
Now, take 2 and divide it by 2. The result is 1, since 2 ÷ 2 = 1.
Once you reach 1, you stop the division process because 1 cannot be divided further by any prime number.
The prime factors of 8 are all the 2s you divided by: 2, 2, and 2. Thus, the prime factorization of 8 is 23.
