Factors of 256 by Prime Factorization
Prime factorization is to express a composite number as the product of its聽prime factors.
- To get the prime factorization of 256, we divide it by its smallest prime factor which is 5.聽256 梅聽 2 = 128,
- Now divide 128 by its smallest prime factor. 128 梅 2 =64
- This process goes on till we get the quotient as 1.聽
- The prime factorization of 256 is shown below in 2 ways: factor-tree method and the upside-down division method.
256 = 2 脳 2 脳 2 脳2 脳 2 脳 2 脳 2 脳 2.聽We can multiply all of these factors thus obtained and get all the possible composite factors as well.

- Factors are never fractions or decimals.
Factors of 256 Solved Examples
-
Example 1:聽Jane plays a game using two聽dice.She makes a two-digit number that turns up on the faces of both聽the dice. For each two-digit number, find out if in any of three rounds she got a common factor of 256 and 144
Rounds Factor pairs Round 1 6, 3 Round 2 1, 6 Round 3 4, 6 Solution:
Let's see the factors of 256聽and 144
- Factors of 256: 1, 2,聽4, 8, 16, 32, 64, 128 and聽256
- Factors of 144: 1, 2, 3, 4, 6, 8,聽9, 12, 16, 18, 24, 36, 48, 72, and 144
Now, let's see the numbers formed by Jolly in both rounds.
- In round 1, Jane聽got the pair 6 and 3. The聽聽2-digit numbers that can be formed are 36 and 63.
36聽 is a factor of 144. However,聽63 is neither a聽factor of 256聽nor a factor of 144.
- In round 2, Jane聽got the pair 1聽and 6. The聽聽2-digit numbers that can be formed are16 and 61.
聽16聽 is a factor of 256 and also聽a factor of 144. On the other hand, 61 is neither a factor of 256 nor 144
- In round 3, Jane got the pair 4聽and 6. The聽聽2-digit numbers that can be formed are 46 and 64.
聽64聽is a factor of 256.聽On the other hand, 46聽is neither a factor of 256 nor 144.
Therefore she got 16 in the 2nd round which is a common factor of 256 and 144. -
Example 2: Sam bought 256聽apples, 128聽oranges, and 64聽avocados聽from the fruit shop. Sam plans to visit an orphanage to provide fruits.Help Sam to prepare 64聽fruit bags in such a way that each bag should have the same number and type of fruit.
Solution:
There are 256 apples, 128 oranges, and 64 avocados.
Sam must prepare 64 fruit bags.
- 256 梅聽 64= 4
- 128 梅 64= 2
- 64 梅 64= 1
Therefore each bag should have 4 apples, 2 oranges, and 1 avocado.
