How to Find the Factors of 8




Factors of 8||What are the Factors of 8?

Today we are going to know how to find out the factors of 8 in just few steps.



              Step-1:


◆The numbers that can divide 8 without remainder are called 8's factors.


◆Rule-1: N's factor is the number that can divide N without remainder.


◆Notice that the factors always includes 1 and itself.


             Step-2:

Notice that the factors always includes 1 and itself.

So,the factors of 8 are 1, ............8.


●A simple way is to find what pairs of numbers multiply to get 8.



●8 = 1× 8



8 is divisible by 1 and 8bwithout any remainder.So,1 and 8 are the two factors of 8.


Proofs:


●8/1=8
●8/8=1




           Step-3:

Already we have gotten two factors of 8 which are 1 and 8.In this step we will find out other factors of 8 by applying the following rule.



◆N's factor is the number that can divide N without remainder.


So,the numbers that can divide 8 without remainder are called 8's factors.


●A simple way is to find what pairs of numbers multiply to get 8.



●8=2 ×4




Proofs:


●8/2=4

●8/4=2







8 is divisible by 2 and 4 without any remainder.


So,the total number of positive factors of 8 (including 1 and itself) are 1,2,4 and 8.


            Step-4

●We have to keep in mind that the factors of an integer include both the positive and negative integers.


So, the factors of 8  include negative numbers or integers. Hence, all the positive factors of 8 can be easily converted to negative numbers .The negative factors of 8 are given below:
-1,-2,-4, and -8.

Look carefully:



(◆Negative times  Negative=Positive) 


◆8= -1 × -8

◆8= -2 × -4


So,the total number of  negative factors of 8  are -1,-2,-4 and -8.

Questions and Answers

●How many factors does the number 8 have?


Ans:The number  8 has 8 factors totally.The number 8 has 4 positive factors and 4 negative factors.


●1,2,4 and 8

 ●-1,-2,-4 and -8.



◆Factor Pairs of 8


Here are the factor pairs of 8.

●A simple way is to find what pairs of numbers multiply to get 8.

●8=1 × 8
●8=2 × 4


Look carefully:



●8=-1 × -8
●8=-2× -4

 The integer 8 has 4 factor pairs.These are given below:

1 × 8,2 × 4

-1 × -8,-2×-4.

SO2 Lewis Structure   Answer: Here is the definition of SO2 Lewis structure. SO2 Lewis structure (sulfur dioxide electron dot structure) is that type of diagram where we show the total 18 valence electrons of SO2 as dots , or dots and dashes(-).In Lewis structure,it is common that a bonding pair of two electrons can be shown by  dash(-) or dots(●●) but a lone pair of two electrons is shown by dots[●●]. In SO2 Lewis structure,there are two double bonds that are going from the atom sulphur to oxygens. In SO2 Lewis structure ,there are totally five lone pairs of electrons.The each  oxygen has two lone pairs of electrons and the sulphur atom has one lone pair of electrons. In SO2 Lewis structure ,the oxygen atoms follow the octet rule but the sulfur atom don't follow the octet rule.It has more than eight electrons. In SO2 Lewis structure,we get nine pairs of electrons.Out of nine pairs of electrons,SO2 has four bond pairs of electrons and five lone pairs of electron...
