What Are the Factors of 8?
The factors of 8 are whole numbers, resulting in a product of 8 when multiplied.
In simpler terms, these numbers can be evenly divided by 8 without leaving any left over.
| Factors of 8 |
|---|
| 1, 2, 4 and 8 |
Recognizing these factors is essential as it simplifies mathematical calculations involving the number 8.
How to Determine the Factors of 8?
Finding the factors of 8 is straightforward using the following essential techniques:
1. Prime Factorization Method
Prime Factorization method involves breaking down a number into prime numbers, which are numbers divisible only by 1 and themselves.
Step 1: Start with the Smallest Prime Number.
Divide 8 by 2: 8 ÷ 2 = 4
Divide 4 by 2: 4 ÷ 2 = 2
Divide 2 by 2: 2 ÷ 2 = 1
Step 2: Write Down the Prime Factorization The prime factorization of 8 is expressed as
8 = 2 × 2 × 2
Step 3: List Down the Factors Factors of 8 are 1, 2, 4, and 8.
2. Factor Tree Method
A Factor Tree visually illustrates the breakdown of a number into its prime factors. Please start with the given number, and divide it until you reach prime numbers, forming branches resembling a tree.
Step 1: Begin with 8 and select 2 as a factor:
8
/ \
2 4
Step 2: Divide 4 by 2:
8
/ \
2 4
\
2
From this tree, the prime factorization of 8 becomes apparent: 2 × 2 × 2.
